Features of plankton community in the Chukchi Sea in August-September, 2017 by N. A. Kuznetsova

“…The northern part of the surveyed area was occupied by the cold water masses from the Arctic Ocean and Beaufort Sea. Large-sized zooplankton dominated here, including copepods Calanus glacialis, C. hyperboreus (this species is an indicator of Atlantic waters) and cold-water hyperiids Themisto libellula. …”

Multi-path Penalty Metric in Underwater Acoustic Communication for Autonomy and Human Decision-making by Howard, Bradli Anne

“…A novel performance metric to improve underwater digital acoustic communication, called Multipath Penalty (MPP), is proposed as an alternative to traditional signal-to-noise ratio (SNR) methods in the context of the Arctic Beaufort Sea. MPP and SNR are compared alongside a third performance metric, Minimum Achievable Error (MAE), which replicates the operation of a channel estimate-based decision feedback equalizer in an acoustic modem. …”

Effects of tones associated with drilling activities on bowhead whale calling rates. by Susanna B Blackwell, Christopher S Nations, Aaron M Thode, Mandy E Kauffman, Alexander S Conrad, Robert G Norman, Katherine H Kim

“…During summer 2012 Shell performed exploratory drilling at Sivulliq, a lease holding located in the autumn migration corridor of bowhead whales (Balaena mysticetus), northwest of Camden Bay in the Beaufort Sea. The drilling operation involved a number of vessels performing various activities, such as towing the drill rig, anchor handling, and drilling. …”

Larval and adult fish assemblages along the Northwest Passage: the shallow Kitikmeot and the ice-covered Parry Channel as potential barriers to dispersal by Caroline Bouchard, Maxime Geoffroy, Mathieu LeBlanc, Louis Fortier

“…Pelagic trawl, bottom trawl, and ichthyoplankton net collections from the US Beaufort Sea to Baffin Bay between 2005 and 2017 are used to map fish distribution along the NWP and identify potential zoogeographic barriers. …”

Arctic Ocean microbial community structure before and after the 2007 record sea ice minimum. by André M Comeau, William K W Li, Jean-Éric Tremblay, Eddy C Carmack, Connie Lovejoy

“…We examined microbial communities over time by using high-throughput sequencing of microbial DNA collected between 2003 and 2010 from the subsurface chlorophyll maximum (SCM) layer of the Beaufort Sea (Canadian Arctic). We found that overall this layer has freshened and concentrations of nitrate, the limiting nutrient for photosynthetic production in Arctic seas, have decreased. …”

Dissolved organic matter composition and bioavailability reflect ecosystem productivity in the Western Arctic Ocean by Y. Shen, C. G. Fichot, R. Benner

“…Dissolved organic carbon (DOC) and total dissolved amino acids (TDAA) were measured in high (Chukchi Sea) and low (Beaufort Sea) productivity regions of the western Arctic Ocean to investigate the composition and bioavailability of dissolved organic matter (DOM). …”

Migration tactics affect spawning frequency in an iteroparous salmonid (Salvelinus malma) from the Arctic. by Colin P Gallagher, Kimberly L Howland, Stephen J Sandstrom, Norman M Halden

“…Otolith strontium and multi-year mark-recapture information were used to characterize associations between migration patterns and spawning frequencies in an anadromous Dolly Varden (Salvelinus malma) population (Rat River, Northwest Territories, Canada) that undertakes a long migration between freshwater spawning/overwintering (Fish Creek; a tributary to Rat River) and marine feeding habitats (Beaufort Sea) (~800 km round trip). Reconstructions of lifetime annual migration histories among otolith annuli was matched to information on reproductive status (current-year 'spawner' or 'non-spawner') that was known in two different, sometimes successive, years for each fish. …”

Environmental drivers of the Canadian Arctic megabenthic communities. by Virginie Roy, Katrin Iken, Philippe Archambault

“…The current project studied for the first time how megabenthic community structure is related to several environmental factors over 2000 km of the Canadian Arctic, from the Beaufort Sea to northern Baffin Bay. Faunal trawl samples were collected between 2007 and 2011 at 78 stations from 30 to 1000 m depth and patterns in biomass, density, richness, diversity, and taxonomic composition were examined in relation to indirect/spatial gradients (e.g., depth), direct gradients (e.g., bottom oceanographic variables), and resource gradients (e.g., food supply proxies). …”
