Iceberg killing fields limit huge potential for benthic blue carbon in Antarctic shallows

first_imgClimate-forced ice losses are increasing potential for iceberg-seabed collisions, termed ice scour. At Ryder Bay, West Antarctic Peninsula (WAP) sea ice, oceanography, phytoplankton and encrusting zoobenthos have been monitored since 1998. In 2003, grids of seabed markers, covering 225 m2, were established, surveyed and replaced annually to measure ice scour frequency. Disturbance history has been recorded for each m2 of seabed monitored at 5–25 m for ~13 years. Encrusting fauna, collected from impacted and nonimpacted metres each year, show coincident benthos responses in growth, mortality and mass of benthic immobilized carbon. Encrusting benthic growth was mainly determined by microalgal bloom duration; each day, nanophytoplankton exceeded 200 μg L−1 produced ~0.05 mm radial growth of bryozoans, and sea temperature >0 °C added 0.002 mm day−1. Mortality and persistence of growth, as benthic carbon immobilization, were mainly influenced by ice scour. Nearly 30% of monitored seabed was hit each year, and just 7% of shallows were not hit. Hits in deeper water were more deadly, but less frequent, so mortality decreased with depth. Five-year recovery time doubled benthic carbon stocks. Scour-driven mortality varied annually, with two-thirds of all monitored fauna killed in a single year (2009). Reduced fast ice after 2006 ramped iceberg scouring, killing half the encrusting benthos each year in following years. Ice scour coupled with low phytoplankton biomass drove a phase shift to high mortality and depressed zoobenthic immobilized carbon stocks, which has persevered for 10 years since. Stocks of immobilized benthic carbon averaged nearly 15 g m−2. WAP ice scouring may be recycling 80 000 tonnes of carbon yr−1. Without scouring, such carbon would remain immobilized and the 2.3% of shelf which are shallows could be as productive as all the remaining continental shelf. The region’s future, when glaciers reach grounding lines and iceberg production diminishes, is as a major global sink of carbon storage.last_img read more

Goldsmiths, University of London Signs Articulation Agreement for SPSCC Graduates Studying…

first_imgFacebook0Tweet0Pin0Submitted by South Puget Sound Community CollegeSouth Puget Sound Community College along with Goldsmiths, University of London has implemented a new articulation agreement for studies in Politics.  The agreement allows qualified SPSCC graduates to transfer into Goldsmiths’ Bachelor of Arts in Politics program with advanced standing.The agreement was formalized earlier this month when representatives from SPSCC met at Goldsmiths, University of London to sign the agreement.This agreement offers numerous benefits to SPSCC graduates, including:Students aiming to attain a bachelor’s degree in Politics can swiftly enter into the program with advanced standing (meaning they will transfer into year two of the three-year program).Students seeking international experiences can enjoy studying in London.Students get work experience as part of the degree; several students have been placed in prestigious agencies, such as the Mayor of London’s office.Current exchange rates offer tuition levels that are comparable to local public universities, such as the University of Washington.Interest in this agreement was sparked in spring of 2015 when Goldsmiths’ International Recruitment Manager, Ms. Louise Blair, contacted SPSCC.  Blair met with Professor of Anthropology and Assistant to the President for Internationalization, Dr. Patrick Chapman, and concluded that an agreement for Politics would be a good fit.  “We live in a globalized age and opportunities like these allow students to broaden their horizons and get a competitive advantage,” said Chapman.This agreement adds to an already robust lineup of international articulation opportunities for SPSCC graduates, such as Business Administration with the Cork Institute of Technology in Ireland and Philosophy with Otago University in New Zealand.  “I am very excited that SPSCC students can now transfer to internationally recognized universities and technical institutes in London, Paris, Ireland, and New Zealand,” said Chapman.  He also stated that further discussions are underway to explore an Anthropology agreement with Goldsmiths, University of London.For more information on SPSCC’s articulation agreements and opportunities, visit spscc.edu/areas/study-abroad.last_img read more

HOLLENDORFER’S LIGHT THE CITY, BAFFERT’S ENCHANTING LADY & BONDE’S RATTATAPTAP LOOM LARGE IN SATURDAY’S GRADE III, $100,000 SANTA YSABEL STAKES AT 1 1/16 MILES

A Kentucky-bred filly by City Zip, Achiever’s Legacy was a first-out maiden special weight winner going five furlongs on turf at Gulfstream Park on June 27. Purchased privately following the maiden score, she was a handy winner of the seven furlong Desi Arnaz Stakes three starts back on Nov. 16 at Del Mar.An even fifth in the Grade I, 1 1/16 miles Starlet at Los Alamitos two starts back on Dec. 13, Achiever’s Legacy would benefit from a fast pace on Saturday. Owned by Campbell, Cellucci, Horowitz and partners, she is 7-2-0-2 overall with earnings of $132,060.Hollendorfer is also well represented by Fox Hill Farms’ Glory, who employed front-running tactics in the mile and one sixteenth California Oaks at Golden Gate Fields Feb. 7, missing by a neck under Russell Baze at odds of 4-5. She was a two length maiden special weight winner two starts back going 6 ½ furlongs at Santa Anita and can be expected to be on or near the early Santa Ysabel lead Saturday.Baffert’s Enchanting Lady, idle since a runaway 6 ¼ length win in the 5 ½ furlong Landaluce Stakes at Santa Anita June 22, was brilliant in victory and is training as though she could be sitting on a top performance first-off the bench. A Kentucky-bred daughter of Tale of the Cat, Enchanting Lady is owned by Kaleem Shah, Inc., and was purchased for $650,000 at Ocala Breeders 2-year-olds in training sale last March. She’ll be making her third career start and is expected to show plenty of early speed in her first two-turn assignment.An impressive 4 ¾ length allowance winner going six furlongs on Jan. 29, Rattataptap, by top sire Tapit, has an abundance of speed but appears tractable in what will be her first start around two turns. A first-out maiden special weight winner from off the pace going 6 ½ furlongs at Del Mar Nov. 29, she was distanced after breaking poorly at 4-1 in her second start, the Grade II, 6 ½ furlong Santa Ynez Stakes on Jan. 3. Owned by Mark DeDomenico, LLC, Jerry Durant and Michael House, Rattataptap has two wins from three starts.A dedicated deep closer, trainer Graham Motion’s Rainha Da Bateria was a Grade III winner going 1 1/16 miles on turf four starts back at Keeneland Oct. 8 and comes off a troubled third, beaten two lengths at 6-5, in the one mile turf Blue Norther Stakes Jan. 1 at Santa Anita. Although there’s no doubt about her ability to route, the Broken Vow filly will try the main track for the first time Saturday. Owned by Three Chimneys Farm, Rainha Da Bateria is 6-2-1-1 with earnings of $184,160.A first-out maiden special weight winner going 6 ½ furlongs down Santa Anita’s hillside turf course Feb. 1, Warren Williamson’s homebred Curlin’s Fox retains the services of Mike Smith and is conditioned by Carla Gaines.
