Abstract:
This data set is a compilation of close to 1000 epifaunal invertebrate sampling stations from over 20 research cruises to the northern Bering Sea (US side), Chukchi Sea (Russian and US sides) and Beaufort Sea (US side) from 1972 to 2012. The vast majority of stations were trawl hauls with a handful of photographic sampling stations. Trawl hauls were conducted with a range of different nets including various otter trawls including the 83-112 Eastern Otter trawl, and a plumb-staff beam trawl with varying mesh sizes ranging from 4 mm in the cod end and 7 mm in the body of the net to xxx. Trawl duration ranged from 1-30 minutes and trawl speed ranged from xx – xx knots. Where available, variables compiled include cruise and station names, locations with water depth, haul and net information, contact information of data holder, as well as total abundance, biomass and taxon richness of epifaunal invertebrates. The latter is biased by varying levels of taxonomic resolution in the source data. The majority of data sets are incomplete, either because the data have not yet been released as is the case for many recent cruises, or because hauls were not quantitative as is the case for some historic data sets. Data on fishes from the same hauls are not reported here. Column headers are explained in the readme file.Changes made to the original data sets as provided by the project contacts or in the data source include, where possible: standardization of abundance to individuals per 1000 square meters; standardization of biomass to kilograms wet weight per 1000 square meters; subtraction of obvious infaunal taxa, eggs and fragments from the taxon count.The research projects or cruise names of the data sets compiled are listed here by year. Also given is the source where Bodil Bluhm (babluhm@alaska.edu) University of Alaska Fairbanks) obtained the data and the archive where fully taxonomically resolved data sets are stored, if anywhere. Where only hard copies where available, data where digitized.WEBSEC 1972, paper copy from Andrew Carey via Susan Schonberg, Bluhm digitized and archived at EOL <http://pacmars.eol.ucar.edu> with metadataFN762 1976, from Howard Feder and Arny Blanchard, archived at www.arcodiv.orgNorton Sound Red King Crab survey 1976-2006, available per request from North Pacific Research Board www.nprb.orgUSCGC Glacier 1977, Bluhm digitized presence/absence from pdf of paper report, to be archived at EOL <http://pacmars.eol.ucar.edu> with metadataRUSALCA 2004, Bluhm/Iken are data holders, archived at www.aoos.org(to go public soon)Hidden Ocean 2005, McDonald/Bluhm are data holders, macrofauna data archived at EOL <http://pacmars.eol.ucar.edu> with metadata, epifauna data not yet archivedHealy 2006-01, Lovvorn, not yet archived, ongoing graduate student thesis projectOshoru Maru 2007, Bluhm /Iken are data holders, archived at www.aoos.org(to go public soon)Oscar Dyson 2007, Bluhm/Iken are data holders, archived at www.aoos.org(to go public soon)Ocean Explorer 2008, Bureau of Ocean Energy Management / Alaska Fisheries Science Center (Logerwell, Rand) / Bluhm are data holders, archived at NOAA/RACE and BOEMOshoru Maru 2008, Bluhm/Iken are data holders, total abundance and biomass only as archived hereCSESP 2009, 2010, Blanchard, archived at www.aoos.org(to go public soon)COMIDA-CAB 2009, 2010, Konar, archived at NODC <http://www.nodc.noaa.gov/cgi-bin/OAS/prd/accession/95566RUSALCA> 2009, 2012, locations only from Bluhm/Iken, analysis in progress as part of graduate thesis, to be archived at www.aoos.orgBeauFish 2011, locations only from cruise log, Konar/Ravelo are data holders, analysis in progress as part of graduate thesis, final report in progress with Coastal Marine Institute, to be available from BOEMCOMIDA Hanna Shoal 2012, locations only from Konar, analysis in progress as part of graduate thesisCSESP 2012, locations only from Blanchard, analysis in progressArctic Eis 2012, locations only from Lauth / AFSC, analysis in progressTransboundary 2012, locations only from Norcross, analysis in progress
