Albatrosses and petrels at South Georgia as sentinels of marine debris input from vessels in the southwest Atlantic Ocean

first_imgIncreasing amounts of anthropogenic debris enter the ocean because of mismanagement in coastal communities and, despite a global ban on deliberate dumping, also from vessels, endangering wildlife. Assessing marine plastic pollution directly is challenging, and an alternative is to use seabirds as bioindicators. Our analyses of long time-series (26-years) revealed substantial variation in the amount, characteristics and origin of marine debris (mainly macroplastics and mesoplastics, and excluding fishing gear) associated with seabirds at South Georgia, and, for two species, long-term increases in incidence since 1994. Annual debris recovery rates (items per capita) were 14 × higher in wandering albatrosses Diomedea exulans, and 6 × higher in grey-headed albatrosses Thalassarche chrysostoma and giant petrels Macronectes spp., than in black-browed albatrosses T. melanophris, partly related to differences in egestion (regurgitation), which clears items from the proventriculus. Although some debris types were common in all species, wandering albatrosses and giant petrels ingested higher proportions that were food-related or generic wrapping, gloves, clear or mixed colour, and packaged in South America. This was highly likely to originate from vessels, including the large South American fishing fleets with which they overlap. Debris associated with the two smaller albatrosses was more commonly shorter, rigid (miscellaneous plastic and bottle/tube caps), and packaged in East Asia. Grey-headed albatrosses are exposed to large and increasing amounts of user plastics transported from coastal South America in the Subantarctic Current, or discarded from vessels and circulating in the South Atlantic Gyre, whereas the lower debris ingestion by black-browed albatrosses suggests that plastic pollution in Antarctic waters remains relatively low. Current plastic loads in our study species seem unlikely to have an impact at the population level, but the results nevertheless affirm that marine plastics are a major, trans-boundary animal-welfare and environmental issue that needs to be addressed by much-improved waste-management practices and compliance-monitoring both on land and on vessels in the south Atlantic.last_img read more

US Coast Guard seized $26 million in cocaine, marijuana

first_imgThe U.S. Coast Guard seized nearly $26 million in cocaine and marijuana at Port Everglades, according to a news release.The drugs were offloaded Wednesday by crews of the Coast Guard Cutter Legare, Winslow Griesser and Cyclone-class patrol ship USS Shamal. The agency said the haul included about 3,900 pounds of marijuana and about 1,100 pounds of cocaine.The Coast Guard seized the drugs from suspected drug-smuggling vessels in the Caribbean Sea as part of a counternarcotics operation.“The fight against drug cartels in the Caribbean Sea requires unity of effort in all phases from detection, monitoring and interdictions, to criminal prosecutions by international partners and U.S. Attorneys Offices in districts across the nation,” the Coast Guard said in the news release.The U.S. Southern Command began enhanced counter-narcotics operations in the Western Hemisphere to disrupt the flow of drugs on April 1, the release said.Numerous U.S. agencies from the Departments of Defense, Justice and Homeland Security cooperated in the effort to combat transnational organized crime. The Coast Guard, Navy, Customs and Border Protection, Federal Bureau of Investigation, Drug Enforcement Administration, and Immigration and Customs Enforcement, along with allied and international partner agencies, play a role in counter-drug operations.The Winslow Griesser is a fast response cutter based in San Juan, Puerto Rico. The Legare, a medium endurance cutter, is based in Portsmouth, Virginia, and the USS Shamal is a Cyclone class coastal patrol ship based in Mayport, Florida.last_img read more

City League Roundup…Perry knocks off Allderdice in final seconds

first_img“Allderdice is a big, strong team,” Perry head coach Marco Corona said. “They played into our strengths as we are a quicker and faster team. We endured and persevered throughout and that is the main thing that led us to a win.”The Dragons were led by Ishmail Swain with 14 points and 8 rebounds. Justin Dobbs and Ben Mickens each added 12 points. “Our slogan on this team is “HAWK-D,” said Allderdice head coach Andre McDonald. “One thing that I can complement our team on is our aggressive intensity on defense and I just like their hard work on each transition. But my hat goes off to Perry. They played like the defending champs that they are.”Perry was down by 10 at the beginning of the fourth quarter before they mounted a comeback led by Harrington. Their junior point guard, Marcus Smith, was slowed down by back spasms and as a result, was held scoreless. He is among the team leaders in scoring this season, averaging more than 17 points a game.Oliver 55, Gateway 45The Bears took care of business against quad-A giant Gateway Jan. 31 at the Pittsburgh Basketball Classic on the campus of Robert Morris University. They have established themselves as one of the teams to beat in the City as they hold the second-best overall and conference records in the league.“We were down two at the half and we wanted to come out and step up things in the second half,” said Oliver head coach Carey White. “That’s what we did. We came out in that second half and started executing. Our defense started taking over and we started to force them into making bad decisions on offense.”Oliver’s senior guard Evan Schell led the way for the Bears with 26 points, including a game-high 7  from behind the arc. Delvon Murray helped the cause with 12 and Phil Ferguson added 11.They made 10 of 13 foul shots in the game, all coming in the fourth quarter.“When it came down to it, we were able to hit the big shots,” said White. “I can’t say enough about our team’s confidence going down the stretch, which makes me excited about what I saw out there.”Craig Banks and Tyler Scott each had 11 points to lead Gateway.Other results:Jan. 26Allderdice 62, Schenley 50Top scorers: (S) Brandon Johnson, 13; Walter Tyler, 12; (A) Justin Dobbs, 16; Brandon McClester, 15; Ben Mickens, 14Carrick 53, Peabody 41Top scorers: (P) Adeneyi Oshoko, 9; (C) Jordan Wilson, 17; Travis Lewis, 13; Rasheed McKamey, 12.Oliver 70, Langley 40Top scorers: (O) Evan Schell, 15; Phil Ferguson, 12; (L) Ronald Carson, 9; Jason McGinnis, 9.Perry 71, Brashear 62Top scorers: (P) Daryl Harrington, 26; Marcus Smith, 16; (B) Henri Chatman, 21; Todd Brown, 15; Elijah Peterson, 13Jan. 29Schenley 92, Westinghouse 59Top scorers: (W) Marcus Falls, 29; Isaiah Naylor, 12; (S) Brandon Johnson, 31; Alonzo Murphy, 14; Camerin Nesbit, 12; Arthur Smith, 12; Mike Robinson, 10Peabody 64, Brashear 53High scorers (B) Henri Chatman, 30; (P) Sharod Green, 17; Adeneyi Oshoko, 16; Marzell Baskins, 10; Rudy Freeman, 10Boys StandingsTeam     Conf.     OverallPerry     10-0        14-1Oliver      8-2        11-4Allderdice      7-3        10-5Peabody      5-5        5-10Westinghouse      4-6        7-9Carrick      4-6        7-9Schenley      4-6        6-9Brashear      2-8        2-13Langley      0-9        0-14Upcoming GamesFeb. 53:15 p.m., Carrick at Perry7:30 p.m., Brashear at Schenley, Allderdice at Westinghouse, Langley at PeabodyWestinghouse girls stillholding on strongAs for the girls, the Lady Bulldogs of Westinghouse are still holding their own and are looking to be a prime target for defeat in the league, going down the stretch.

Three in a row for JC – Dawkins’ late show does it again

first_imgDonovan Dawkins scored another late goal to fire defending champions Jamaica College (JC) to a third successive hold on the coveted ISSA-FLOW Olivier Shield, the symbol of all-island schoolboy football supremacy, at the Stadium East field yesterday. Dawkins, who broke the hearts of St George’s College when he found an 89th-minute winner in the recent Manning Cup final, was again the star of the show with a 90th-minute clincher to stun daCosta Cup champions St Elizabeth Technical (STETHS). The goal capped a come-from-behind 2-1 victory for JC, who sealed their 20th hold on the trophy. The STETHS camp was left fuming after the defeat, as they accused the match officials of denying them at least three clear penalties. Dwayne Foster’s 30th strike put STETHS ahead, but the Old Hope Road-based JC rallied in the second-half with goals from Tyrique McGee (50th) and Dawkins. JC coach Miguel Coley admitted they were poor in the first period, but said a firm team talk at half-time and a few adjustments made the difference in the second half. “Football is 90 minutes and more. The first half was difficult. We were down 1-0, but we have shown over the years that we are resilient. We knew STETHS wouldn’t last the entire game, and we got space and hurt them,” he said JC became the first school to win three straight Oliver Shield crowns since Vere Technical won four titles from 1967 to 1970, and Coley was proud of this achievement. FANTASTIC FEAT “It’s a fantastic feat for everyone behind this team … we are the best team (this season). We are an all-round team. We are not the most flashy, but football encompasses everything, and we were the most mental team. We are very organised defensively, and it paid off for us this year,” he added. A set-piece on 30 minutes put the rural champions in front. Foster’s free kick eluded everyone before lodging inside the far post. Five minutes into the second half, a brilliant strike from McGee pulled JC level. Dawkins and Zeron Sewell wasted great two opportunities to give them the lead. They were not to be denied, however, as Ronaldo Brown slipped a pass to Dawkins, who tucked the ball past Jahmali Waite on full time. It was STETHS’ third defeat in their last three Oliver Shield finals (2009, 2013 and 2015). STETHS’ coach Omar Wedderburn was upset as he thought the game was not decided by the players. “It’s a loss that I really feel upset over,” Wedderburn said as he pointed to mistakes made by the match officials.last_img read more

New bell brings hope to North West Cancer Centre

first_imgA new ‘End of Treatment Bell’ has been installed at the North West Cancer Centre in Derry to provide a symbol of hope for patients.Patients who are coming to the end of their cancer treatment can experience mixed emotions. Happiness and relief that their chemotherapy and or radiotherapy is complete but worry and apprehension about the future.Going through treatment for many weeks, patients who attend the North West Cancer Centre at Altnagelvin Hospital, will have bonded with cancer centre staff and forged lasting friendships with other patients together on their cancer journey. The North West Cancer Centre has recently installed an ‘End of Treatment Bell’ for cancer patients who choose to publically celebrate and mark the end of their treatment. The bell is situated within the radiotherapy waiting area.Patients who finish their treatment, either radiotherapy or chemotherapy, can ring the bell to signal the end of their treatment and to symbolise their hope for the future.From Left Paula Powell, Martina O’Brien and Elaine Reilly, Radiotherapy Services Manager.Many Donegal cancer patients have had treatment at Altnagelvin. Since the opening of the North West Cancer Centre until end of October 2018, 162 patients from the Republic of Ireland have received radiotherapy locally.Lesley Mitchell, Macmillan Lead Nurse, Cancer Services at the Western Trust said: “The bell is a symbol of hope for our patients. It will give patients who have finished their treatment the opportunity to mark it. It may also be helpful and inspiring for other patients who are currently undergoing treatment. “The North West Cancer Centre opened in November 2017 and has made a huge difference to the lives of people, who would have previously had to travel to Belfast or Galway for their treatment.“I am delighted that we can now give our patients an opportunity to mark their end of their treatment journey. Finishing treatment can be very emotional for many patients and some may choose to mark this milestone privately or in other ways but the option of ringing the bell will be available for any patients who choose to do so.”The bell was donated to the North West Cancer Centre by Gabrielle Hall, who is a nurse in England and had seen the bell in use at her local cancer unit.Gabrielle’s grandfather, John Doran from Derry, was going through chemotherapy at the North West Cancer Centre and she wondered if he would get an opportunity to ring the End of Treatment Bell, following his course of treatment. When she discovered the Cancer Centre didn’t have a bell, Gabrielle set about organising and arranging for one to be installed.From Left Mr John Doran and Margaret Doran from Derry, whose Granddaughter and Niece donated the bell. Also in the picture is Lesley Mitchell Macmillan Lead Nurse, Cancer Services.John attended the launch of the bell, he said: “As a family, it is our hope that the End of Treatment Bell will allow patients to mark milestones at the end of their treatment and look to the future. It’s a very simple gesture but it gives an opportunity to mark the occasion and provide hope for patients, their family and Cancer Centre staff. I was delighted to attend the launch of the End of Treatment Bell and be one of the first people to give it a ring.” As well as Mr Dolan, Carolyn Rutherford from Eglinton, coincidentally a member of staff at the North West Cancer Centre, finished her cancer treatment recently and took the opportunity to ring the bell to celebrate this. It was particularly poignant that she got to do this in the presence of her colleagues and friends.From Left North West Cancer Centre staff, Margaret McCloskey, Lesley Mitchell, Carolyn Rutherford, Rebecca Durnin, Maria McBrearty and Leonie Hendry.New bell brings hope to North West Cancer Centre was last modified: May 30th, 2019 by Rachel McLaughlinShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window)Tags:North West Cancer Centrelast_img read more

Why Is It So Humid In Here?

first_imgWhat about fans in the bathroom?Aaron Becker wonders whether ventilation in the bathrooms and kitchen has something to do with it.Is the kitchen exhaust fan, for example, a recirculating type or vented to the outside? And is all of the moisture generated in the bathroom supposed to be handled solely by the HRV?“How about some simple tests?” Becker says. “Run the showers (one at a time) and place a humidity gauge in the outdoor exhaust stream vent to see if there is a difference before and after. Do the same thing with the kitchen exhaust venting.”Another place to check: if there is a basement sump, it should have an airtight sump lid, to make sure that isn’t the source of moisture in the basement.The kitchen fans theory, as it turns out, was a dead end. Chappell-Dick replies there is no kitchen exhaust fan, and no separate bathroom exhaust fans, either. CONSTRUCTION DETAILS Try a portable dehumidifierWhile he gives the house a chance to dry out on its own, both David Meiland and Jin Kazama suggest Chappell-Dick try a portable dehumidifier.Meiland wonders whether running a dehumidifier for a short period of time might knock the relative humidity down. He suggests running it in the basement, then moving it upstairs to see what happens.Also, Meiland adds, if Chappell-Dick has separate fans in the bathrooms, he might try running those for extended periods of time to see what happens.“Seems like winter air in Ohio should be fairly dry, so it should make a difference,” he says.And there’s no major energy penalty for running the dehumidifier inside during the winter, Kazama adds, because the heat it produces won’t be wasted.“That said,” he adds, “I do not know the conditions at your place, but as soon as we move in heating territory here (mid Quebec), it’s hard to get anything above 40 percent RH… This calls for serious investigation.” Building Plans for a Dry, Radon-Free Foundation Preventing Water Entry Into a HomeDesigning a Good Ventilation SystemHRV or ERV?How Much Fresh Air Does Your Home Need?Ventilation Rates and Human HealthAll About Dehumidifiers Q&A: Dehumidification vs. Ventilation in an Existing House From the sound of it, Andy Chappell-Dick has left no stone unturned in his quest to keep the air inside his house comfortably dry.His extremely tight new house in northern Ohio (Climate Zone 5) is built with structural insulated panels, and heated and cooled with a pair of ductless minisplit heat pumps. For ventilation, Chappell-Dick has a Venmar Kubix heat-recovery ventilator that pulls exhaust air from two small bathrooms and supplies fresh air to two upstairs bedrooms with a flow rate of between 40 and 80 cubic feet per minute (cfm).“All my plumbing traps are good,” he writes in a Q&A post at GreenBuildingAdvisor. “We hardly take any showers. We cook some, not a lot. No dishwasher. No aquarium. No dryer — we dry clothes offsite. I figure all the entrained construction moisture is long gone.”And yet the interior air isn’t really very dry. Chappell-Dick has seven hygrometers around the house to measure relative humidity, and none of them seems to drop below 47 percent, typically reading about 60 percent.Does he have a bum HRV?“Even in a worst-case scenario of compromised or short-circuiting airflow, say 25 cfm, shouldn’t this unit be capable of doing several total air changes per day? It was a damp December, but we had some cold, dry days that didn’t move the needles much.“In such a tiny tight house, does the humidity produced by just the two of us require a dehumidifier in addition to the HRV? Is there some moisture source we’re overlooking? Or is there typically a long lag in getting the house’s contents — tons of drywall and flooring and interior framing and everything — to dry out so it’s no longer the source?” RELATED ARTICLES center_img Give it some more timeDon’t hit the panic button yet, says GBA senior editor Martin Holladay. It may take a couple of months of winter ventilation before interior moisture levels start to fall.“Summertime ventilation doesn’t lower the humidity much, and in many U.S. climates actually raises the indoor humidity,” he writes. “So you need to have a few months of winter ventilation before you can be sure what is going on.”But Holladay, like others responding to the post, wonder about the possible role the concrete in Chappell-Dick’s basement may be playing. Concrete contains a lot of water that must evaporate after it cures and, Holladay adds, is it possible that the contractor forgot to put a layer of polyethylene plastic or rigid foam insulation beneath the basement slab to block moisture from migrating upward.GBA reader Flitch Plate agrees that a single year might not be long enough for all of the moisture accumulated during construction to dissipate.“I would not count on all the construction moisture to be fully evaporated,” he says. “I would monitor but not make any decisions until you have another year under your belt.” Chappell-Dick’s battle with high indoor humidity is the topic for this Q&A Spotlight. Refocusing attention on the basementJill Fussell turns the conversation back to the basement, based on her own experience in a house of similar size built in the Austin, Texas, area during a wet winter a few years back.“The slab had been poured and only allowed to dry a day or so before framing started, which I attribute to the high relative humidity (60 percent or more),” she writes. “Luckily I had a portable dehumidifier that I ran the first year, and finally the RH dropped into the 40-45 percent range.”She asked an architect friend to computer how much water the basement slab would give up during the first year of occupancy, and his answer was 600 gallons.“So, based on the size of your house and probably the size of the basement associated with it, I would venture a guess that the curing of the basement concrete is the reason you have high RH,” Fussell says. “I would suggest running a portable dehumidifier in the basement for at least a full year as the concrete cures. “One last step would be to check on how often the HRV runs. In Fussell’s case, the HRV was running on factory settings that made it cycle too frequently, “bringing in too much relatively moist air for the rather efficient HVAC to condense and dispose of (I don’t have a dehumidifier on the HVAC).” Our expert’s opinionHere’s what GBA technical director Peter Yost has to say:Andy Chappell-Dick and I had quite a few e-mail exchanges to try and figure out why his interior relative humidity (IRH) seems higher than it should be, given all the conditions of his structure and mechanicals. Here is what we know, in addition to what is covered above:Andy is an admitted “tech nerd” and is a very engaged owner, keeping very good track of how his home operates and manually engaging mechanical equipment for optimal performance.All of Andy’s hygrometers are “el cheapo,” eBay purchases of about $4 each. While their precision seems to be about ±3 percent, I know from experience that this type of inexpensive hygrometer can read as much as 10 percent different than actual RH (so lack of accuracy despite apparent precision). The window condensation tells us the indoor RH is higher than what we should expect, but we don’t know really how much higher it is running. (There is a big difference between 40% and 60%).The Venmar HRV seems to be operating properly. Without an interior source of moisture, Andy is operating his system in such a way that wintertime IRH should not be running at 40 percent and above.We could not determine any other source of moisture besides moisture of construction. Andy’s home construction started in April 2013 and they moved in in December 2013.So, the question is: almost two years into a home’s life, can the concrete’s vapor emission rate still be enough to cause higher indoor RH than we would expect?First, there is a GBA reference that helps with this question: Moisture Sources, Relative Humidity, and Mold. And in Andy’s case, we can use the psychrometric chart to calculate how much water in his volume of air results in changes in indoor RH: Andy’s home measures about 10,500 cubic feet, with a dry air weight of about 788 pounds (1 cubic foot of dry air @ 70°F = 0.075 pounds). That means that to move from 20 percent to 40 percent IRH, adding only about 2 pounds (or pints) of water is needed, and to move from 40 percent to 60 percent only about 2.4 pounds of additional water is required.In general, concrete continues to emit measurable amounts of water vapor (with no added source of wetting) for at least 3 years and in the range of the amounts of water cited above (see Figure 2 in Moisture in Concrete). And if you add to that the admittedly tiny amounts of water generated by occupants, we do have enough moisture to significantly elevate indoor RH in tiny, tight homes or apartments, like Andy’s.I think that Andy needs to use his dehumidifier as the most efficient way to handle his elevated wintertime indoor RH for at least another year but that over time the vapor emitted as moisture of construction will move down in such a way that optimal use of his HRV will move his average wintertime indoor RH down to a more typical range for his climate and building characteristics.GBA invites Andy to come back at us (or more rightly, I guess, me) in a year for a “Click and Clack” sort of “Stump the Chump” followup to see if we got this right.And by the way, Andy’s situation — moisture problem in a very airtight structure — is not an anomaly; even small amounts or sources of moisture can become problematic in really airtight structures.last_img read more
