title: Physiological Constraints to Diving: Defining the Capacity of Belugas to Alter Foraging Behaviors in Response to Habitat Degradation

description: The data were collected to describe how the physiology that supports diving of beluga whales matures after birth. Specifically, body mass, hemoglobin content (blood oxygen store) and myoglobin content (muscle oxygen store) were measured for belugas at birth through adulthood. The goal of this investigation was to quantify age-specific morphological parameters (body mass) and physiological parameters [oxygen stores in the blood (hemoglobin) and muscle (myoglobin)] to support the determination of age-specific aerobic dive limits (cADL). cADLs define age-specific abilities for transiting under sea-ice and diving to depth for prolonged durations to support foraging activities. Long-term, longitudinal measurements of body mass and hematology (red blood cell number, hemoglobin, hematocrit, mean corpuscular volume, mean cell hemoglobin, and mean cell hemoglobin content) from birth through adulthood in belugas housed at John G. Shedd Aquarium provided historical records of these parameters. Male and female data were analyzed separately. Muscle samples were obtained from neonatal through adult beluga strandings (Cooke Inlet), subsistence hunts (Pt. Lay), and deaths of belugas housed at John G. Shedd Aquarium (founding animals from Churchill River in western Hudson Bay). These muscle samples were analyzed in the laboratory for myoglobin content and acid buffering capacity. Due to limited sample size, data from male and female specimen were combined to provide age-specific myoglobin levels, as has been done in previous investigations on cetaceans. Age-specific myoglobin contents were also used in the determination of the cADLs. Ultimately, calculations of age-specific aerobic dive limit provided for age-specific maximum dive depth, and age-specific submerged search times just below the waters surface (as if navigating under sea ice) and at dive depths of 200 m, 300 m, and 400 m. This dataset consists of 7 CSV files: gompertz_growth_values.csv, female_beluga_cadl.csv, age-specific_dive_capacity_1.csv, age-specific_dive_capacity_2.csv, neonate_values.csv, and male_beluga_cadl.csv.

title: Shell lengths of pteropod, Limacina helicina antarctica, collected from the PAL LTER sediment trap along the Western Antarctic Peninsula, 2004 - 2018, and from net tows 2017-2018.

description: Pteropod, Limacina helicina antarctica, is an abundant zooplankton along the Western Antarctic Peninsula (WAP) and prey for higher trophic organisms. Changes in the pteropod (pelagic snail) phenology (life history) have important implications for regional food web dynamics. Pteropod shell lengths were collected from the PAL LTER sediment trap located along the northern continental shelf of the PAL LTER sampling grid, 2004-2018. PAL LTER has deployed a time-series trap near 64.5° S, 66.0° W since late 1992. The trap is moored in 300 m depth and collects sinking particles at 170 m. Pteropod samples are stored in 21 sample collection bottles on the sediment trap that were prepared with a Milli-Q deionized water rinse and filled with 7.5 g NaCl l-1 solution and 2% borate-buffered formalin in filtered seawater (34 ppt), with a final salinity concentration of 41 ppt. L. h. antarctica shell lengths also collected during the PAL LTER 2018 January offshore cruise and for four months at Palmer Station, Anvers Island (November 2017 to February 2018). L. h. antarctica and all other macrozooplankton collection on the PAL LTER cruise are performed with a 2 m square frame Metro net (700 µm mesh), towed obliquely to a depth of 120 m. At Palmer Station, pteropods are collected with a 1 m x 1 m square frame Metro net (700 µm mesh) and a 1 m diameter ring net (200 or 500 µm mesh), towed obliquely to a depth of ~50 m. Shell lengths are determined by measuring from the opening of the shell aperture directly across the diameter of the shell. The shell lengths analyzed within the WAP region are used to determine phenology patterns in pteropod population dynamics and changes thereof over time.

title: Climate, and Ecological Effects on Pacific Halibut Size-at-age: Cumulative effects of size-selective fishing on size-at-age in the Gulf of Alaska and Bering Sea

description: We developed an age- and size-structured equilibrium model using the software package R to examine the long-term relationship between fishing mortality and size-at-age of Pacific halibut. We limited our study to International Pacific Halibut Commission (IPHC) regulatory areas in the Gulf of Alaska (2B, 2C, 3A, and 3B), because these areas provide the greatest contrast in terms of historical fishing mortality and changes in size-at-age. Primary inputs to the equilibrium model included sex and area-specific von Bertalanffy growth parameters that were estimated externally using fisheries-independent observations of halibut length-at-age collected by the IPHC collected from 1980 to 1989, when halibut size-at-age was at its peak. This growth curve, which defines mean size-at-age and variability in size-at-age, was used to generate a series of “growth-type groups,” or groups within a cohort that differ in growth and relative abundance. Additional model inputs included parameters associated with maturity, natural mortality, length-weight allometry, and recruitment Model results were evaluated in terms of changes in mean size-at-age with fishing mortality under equilibrium conditions. Model outputs used for Sullivan (2016) include a data frame of predicted weight-at-age under varying equilibrium fishing mortalities, size limits, and discard mortality rates. This model was coded in the statistical software program R version 3.2.5 (R Core Team 2016). Model results are stored as a dataframe within R but could be exported as a csv or text file.

title: Large-scale environmental data recovery and analysis for the North Pacific – Arctic region, 2014-2015

description: This study focused on the large-scale recovery of Arctic and North Pacific historical environmental data—amounting to millions of individual observations—and making them available for new research, such as extended retrospective analysis (reanalysis) to study a range of lower-frequency climate phenomena and better understand their impact on the Arctic environment. This Excel spreadsheet is a manifest of 105,315 high resolution digital images of selected vessel logbooks that were digitized by University of Washington staff and student-interns from July 1, 2014 to June 30, 2015 at imaging stations at the National Archives (in Washington, D.C. and College Park, MD locations). The original manuscripts are held at Archives 1 and 2, and the U.S. National Archives (NARA) maintains the digital images on the NARA computer system accessible via the national catalog. The temporal range of the collection spans 1844 to 1960 (nominal) and includes archival assets for federal vessels, including the US Navy and US Coast Guard. Geographic coverage is global, with an emphasis on the North Pacific and Arctic. The information contained in the digitized vessel logbooks includes historical weather, sea ice, and other environmental observations of the Arctic. This collection is an extension of digitizing effort that occurred under NPRB Project 1124, Environmental data rescue in the North Pacific and Arctic through a citizen-science initiative, and NPRB Project 1226, Crowd sourcing large-scale environmental data recovery for the North Pacific – Arctic region from 1850 to the satellite era.

title: Glider based real-time monitoring of marine mammals in the Arctic, 2016

description: Shipboard observations of marine mammal distribution and habitat are expensive and logistically challenging to collect in Arctic waters. Port facilities are minimal and access to appropriate vessels for spending extended periods of time at sea is extremely limited. Autonomous platforms like gliders provide the capability to collect both oceanographic and passive acoustic data for far longer periods of time (weeks to months) and at significantly reduced costs than traditional shipboard or aerial surveys. We have developed a system to record, detect, classify, and remotely report Arctic and sub-Arctic marine mammal calls in real time from Slocum ocean gliders based on the digital acoustic monitoring (DMON) instrument and the low-frequency detection and classification system (LFDCS). The system has been used several times in the northwest Atlantic Ocean and was successfully demonstrated for Arctic research during two pilot studies in the Chukchi Sea during September 2013 and 2014. Deployments to date have been short (1-3 weeks), but the capability exists for much longer missions. Our objective is to conduct an 8-10 week survey of the northeastern Chukchi Sea using a G2 Slocum glider to (1) examine the distribution, occurrence, and habitat of marine mammals using in-situ passive acoustic and oceanographic data collected by the glider, and (2) demonstrate the near real-time detection and reporting capability of the system. We hypothesize that some Arctic species associate with a front separating Bering Sea water and Alaska Coastal Current water to take advantage of aggregations of either pelagic or benthic prey. We further hypothesize that marine mammal community composition will change predictably with the strong spatial variability in oceanographic properties found in this region. We anticipate that these predictions will improve efforts to (1) mitigate impacts on marine mammals by human activities and (2) forecast changes in species distributions caused by climate change.

title: Determining bulk distribution of calling depths of bowhead and northern right whales using non-linear signal processing methods in the Beaufort Sea, 2010

description: The project estimated depths at which bowhead whales made calls, using passive acoustic source data recorded from 2008-2010 at several geographic locations in the Beaufort Sea. Raw acoustic data used were collected by Greenridge Sciences using hydrophones. The Beaufort dataset contains whale calls recorded between August 10-October 10 each year from 2008-2014. The data files contain dates, times, and depths of whale calls, as well as range to closest instrument. The data files for this project include an input file (ASCII text file named ‘inp_file.env’) to the acoustic model that encodes parameters describing the acoustic propagation environment and an output file (ASCII text file named ‘‘Chapter3_inputs_and_outputs.txt’) that combines the inputs from the automated detector program with the final depth estimates from the entire procedure. This data was collected to determine bulk distrubution of calling depths of bowhead whales in the Beaufort Sea.

title: Assessing abundance of beluga whales in Bristol Bay using genetic mark-recapture methods, 2002-2011

description: This project estimated the abundance of beluga whales within the Bristol Bay stock using genetic mark-recapture methods and combined genetic data with aerial survey data to develop an unbiased correction factor for use in future aerial surveys. The project was started in 2004 by the Alaska Beluga Whale Committee, which funded sample collection from 2004 until 2012 and genotyping from 2004 until 2011, and continued through funding from the North Pacific Research Board (NPRB 1516) from 2015 through 2017. The data for this project were generated using genetic markers from skin biopsies of beluga whales Bristol Bay from 2002 to 2011 using mark-recapture methods. Data from this project consists of 2 .csv data files archived here (NPRB_1516_Bristol_Bay_beluga_whale_abundance_data_sample_list.csv and NPRB_1516_Bristol_Bay_beluga_whale_abundance_data_matching_file.csv).
