Off-shelf waters cover 66% of the planet. Growing concerns about the state of natural resources in these waters, and of future threats have led to a growing movement to improve management and conservation of natural resources. However, efforts to assess progress and to further plan and prioritise management interventions have been held back in part by the lack of a comprehensive biogeographic classification for the high seas. In this work we review existing efforts at classifying the surface pelagic waters of the world’s oceans and we present a synthesis classification which draws both on known taxonomic biogeography and on the oceanographic forces which are major drivers of ecological patterns. We describe a nested system of 37 pelagic provinces of the world, nested into a system of four broad realms. Ecologically we have also differentiated a system of 7 biomes which are spatially disjoint but united by common abiotic conditions creating physiognomically similar communities. This system builds on existing work and is further intended to align closely with the coastal biogeographic regionalisation provided by the Marine Ecoregions of the World classification. It is hoped that it will provide a valuable tool in supporting threat analysis, priority setting, policy development and active management of the world’s pelagic oceans.
We present an update of the ‘key points’ from the Antarctic Climate Change and the Environment (ACCE) report that was published by the Scientific Committee on Antarctic Research (SCAR) in 2009. We summarise subsequent advances in knowledge concerning how the climates of the Antarctic and Southern Ocean have changed in the past, how they might change in the future, and examine the associated impacts on the marine and terrestrial biota. We also incorporate relevant material presented by SCAR to the Antarctic Treaty Consultative Meetings, and make use of emerging results that will form part of the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report
Leads are cracks in sea ice that often form due to deformation. During winter months leads expose the ocean to the cold atmosphere resulting in supercooling and the formation of frazil ice crystals within the mixed layer. Here we investigate the role of frazil ice formation in leads on the mass balance of the sea ice pack through the incorporation of a new module into the Los Alamos sea ice model (CICE). The frazil ice module considers a initial cooling of leads followed by a steady state formation of uniformly distributed single size frazil ice crystals that precipitate to the ocean surface as grease ice. The grease ice is pushed against one of the lead edges by wind and water drag that we represent through a variable collection thickness for new sea ice. Simulations of the sea ice cover in the Arctic and Antarctic are performed and compared to a model that treats leads the same as the open ocean. The processes of ice formation in the new module slows down the refreezing of leads resulting in an longer period of frazil ice production. The fraction of frazil-derived sea ice increases from 10% to 50%, corresponding better to observations. The new module has higher ice formation rates in areas of high ice concentration and thus has a greater impact within multiyear ice than it does in the marginal seas. The thickness of sea ice in the central Arctic increases by over 0.5 m whereas within the Antarctic it remains unchanged.
Little is known about colonization of remote island coasts by marine invertebrates, other than corals. The structure of hard substrata assemblages was investigated across Ascension Island’s littoral zone in comparison with other sites. Arrays of acrylic panels were deployed at two sites for 2 years at Ascension Island to measure subtidal recruitment. Colonization of panels at Ascension I. was low, though space occupation, abundance and richness varied considerably. After ~1 and 2 years Ascension panels were <17 and <37% covered by fauna and each had 30% covered, with>76 recruits per 100 cm2 and with bryozoans well represented after 1 year. Across-littoral surveys of established macrofauna at five remote islands (Ascension I., Easter I., Azores, South Georgia and Signy I., Antarctica) revealed similar trends of a rich sublittoral and lower littoral reducing drastically up-shore; molluscs dominating abundance and species numbers, whilst polychaetes, crustaceans and echinoderms were well represented. Established sessile animals occurred patchily at a mean density of 8.26 m−2 but recruits had mortality levels >99%. Polar or remote temperate/tropical sites are typically less colonized than at non-remote, low latitudes but the lowest levels reported are at remote polar sites. Reduced colonization at Ascension island reflects remoteness.
April 1, 2018 /Sports News – National Las Vegas Golden Knights honor victims from last year’s mass shooting FacebookTwitterLinkedInEmailiStock/Thinkstock(LAS VEGAS) — Before the start of Saturday night’s game, the NHL’s Las Vegas Golden Knights honored the 58 victims from the Oct. 1 shooting.Team owner Bill Foley, general manager George McPhee and defenseman Deryk Engelland stood alongside the family of victim Neysa Tonks, which was there to represent the families of the 58 killed in the Oct. 1, 2017, shooting on the Las Vegas strip, as the team raised a gold and black “Vegas Strong” banner to the rafters above T-Mobile Arena.The banner displayed the names of the 58 victims, along with 58 stars.“Tonight, we fly 58 stars in the sky as a reminder that the 58 will always be with us,” the arena’s announcer said as the banner was rising.The team also took to Twitter, writing, “The 58 will always be with us #VegasStrong.”The Golden Knights also retired jersey No. 58 to honor the victims because “the Las Vegas Golden Knights have decided that the number 58 will never be worn,” according to the arena’s announcer.Along with the jersey retirement and banner, the Sin City team lit up the ice with the names of the victims.This isn’t the first time the team honored the victims of the shooting. During their home opener on Oct. 10, 2017, the Golden Knights lit up the ice with the names of the victims and kept the boards along the ice advertisement-free, instead writing “Vegas Strong.”There were 58 people killed and hundreds more injured when gunman Stephen Paddock allegedly opened fire on a country music festival from the Mandalay Bay Hotel across the street. Paddock killed himself while authorities closed in on his hotel room. It was the deadliest mass shooting in modern U.S. history.The expansion Knights are wrapping up a historic first season. They beat the San Jose Sharks on Saturday night to improve to 50-22-7 on the season. The team clinched first in the Pacific Division on Saturday, and their 107 points are second in the Western Conference.Copyright © 2018, ABC Radio. All rights reserved. Written by Beau Lund

FacebookTwitterLinkedInEmailLOGAN, Utah-Saturday, as part of their Homecoming festivities, Utah State football will honor three previous championship teams, the Aggies’ squads from 1978, 1993 and 2013.The 1978 team, coached by Bruce Snyder, tied for first in the Pacific Coast Athletic Association (the predecessor to the Big West) with a record of 7-4 and was the Aggies’ first conference championship team since 1961.This team featured former Detroit Lions signal-caller Eric Hipple and former Denver Broncos and Seattle Seahawks tailback Rick Parros.The 1993 team was coached by Charlie Weatherbie and tied for first in the Big West. This squad was led by legendary Canadian Football League quarterback Anthony Calvillo, primarily known for his days with the Montreal Alouettes. He also played with the CFL’s Las Vegas Posse and Hamilton Tiger-Cats.Calvillo, who retired in 2013, is currently the all-time North American pro football leader in passing yards at 79,816 yards. That is 7,713 yards ahead of NFL all-time leading passer Drew Brees of the New Orleans Saints.Current USU head football coach Matt Wells played on the 1993 team and his 2013 team, the first he coached at Logan, is known for winning the Mountain West Conference’s Mountain Division.After losing to Fresno State in the league championship game, the 2013 Aggies went on to beat #24 Illinois in the SDCCU Poinsettia Bowl at San Diego.
