AFSC/RACE/GAP/McConnaughey: Fishpac Projects-2008-QINSy

The broad scope of the Essential Fish Habitat (EFH) mandate requires an efficient process for describing and mapping the habitat needs of federally managed species.  For example, research indicates surficial sediments affect the distribution and abundance of many groundfish species, yet traditional sampling with grabs and cores is impractical over areas as large as the Bering Sea shelf.  Acoustic tools are suitable for large-scale surveying and show great promise as a substitute for direct-sampling methods, but they have not been proven useful for EFH purposes.

AFSC/NMML: Bowhead Whale Feeding Ecology Study (BOWFEST): Aerial Survey in Chukchi and Beaufort Seas, 2007-2011

The Bowhead Whale Feeding Ecology Study (BOWFEST) was initiated in May 2007 through an Interagency Agreement between the Bureau of Ocean Energy Management (BOEM) (formerly Minerals Management Service (MMS)) and the National Marine Mammal Laboratory (NMML). This was a multi-disciplinary study involving oceanography, acoustics, tagging, stomach sampling and aerial surveys and included scientists from a wide range of institutions (Woods Hole Oceanographic Institution (WHOI), University of Rhode Island (URI), University of Alaska Fairbanks (UAF), University of Washington (UW), Oregon State University (OSU), North Slope Borough (NSB), and NMML).  The data described and presented here are only from the aerial survey component of this larger study.  The focus of the aerial survey was to document patterns and variability in the timing and locations of bowhead whales. Using a NOAA Twin Otter, scientists from NMML conducted aerial surveys from mid-August to mid-September during this five year study between years 2007-2011.  Surveys were conducted in the BOWFEST study area (continental shelf waters between 157 degree W and 152 degree W and from the coastline to 72 degree N, with most of the effort concentrated between 157 degree W and 154 degree W and between the coastline and 71 degree 44'N).

Arctic Aerial Calibration Experiments (ACEs), Beaufort Sea, 2015

The Arctic Aerial Calibration Experiments (ACEs) study was designed to evaluate the ability of UAS technology (i.e., airframe, payloads, sensors, and software) to detect cetaceans, identify individuals to species, estimate group size, identify calves, and estimate density in arctic waters, relative to conventional aerial surveys conducted by human observers in fixed wing aircraft and to photographic strip transect data collected from the manned aircraft.  The ACEsâ imagery described here was collected and analyzed in order to conduct a 3-way comparison of data and derived statistics from the following:  
â¢	Observers in the manned aircraft;
â¢	Digital photographs from cameras mounted to the manned aircraft;
â¢	Digital photographs from cameras mounted to the Unmanned Aerial Vehicle (UAV).

AFSC/NMML: North Pacific Killer whale genetic dataset, 1990-2010

The difficulties associated with detecting population boundaries have long constrained the conservation and management of highly mobile marine species, especially for wide-ranging cetaceans such as killer whales (Orcinus orca).  In this study, we use molecular genetic data to test a priori hypotheses about population subdivisions generated from a decade of killer whale surveys across the northern North Pacific. A total of 462 skin biopsies were collected from free-swimming killer whales from 1990 to 2010 between the northern Gulf of Alaska in the east and the Sea of Okhotsk in the west, representing both the piscivorous resident and the mammal-eating Biggs (or transient) killer whales. Geographic patterns of genetic differentiation were supported by significant regions of genetic discontinuity providing evidence of population structuring within both lineages, and corroborating direct observations of restricted movements of individual whales. In the Aleutian Islands (Alaska), population strata were largely delimited by major oceanographic boundaries for resident killer whales. In contrast, subdivisions among Biggs killer whales indicated multiple genetic clusters in the Eastern Aleutians and Bering Sea. The presence of sympatric genetic clusters within Biggs whales suggests the presence of isolating mechanisms other than geographic distance within this highly mobile top predator.

AFSC/RACE/GAP/McConnaughey: South Arctic Reconnaissance-2012-GIS

A custom designed Klein 7180 towed sonar was deployed from the NOAA Ship FAIRWEATHER to determine its value of acoustic backscatter as a habitat defining character. A Sonardyne Fusion USBL system was used to estimate underwater positioning of the towfish using an omnidirectional Wideband submini beacon operating in external trigger mode. Navigation data were logged in QINSy and exported into a text file. The towfish positions were then smoothed in Matlab using a custom script that implemented a weighted Hamming filter, using a window of 11 data points. These points represent the smoothed USBL navigation data for the Klein 7180 towfish during the Arctic reconnaissance transit from Dutch Harbor to Kotzebue. These smoothed towfish navigation data, however, will NOT ultimately be reinserted back into the sonar files for mosaicking and analysis. Rather, another navigation smoothing routine will be used for the final product.

AFSC/ABL: Gulf of Alaska and Bering Sea Capelin Microsatellite data, 2005 & 2007

Capelin are important forage fish in Alaska for marine mammals, birds, and predatory fish.  Capelin prefer cold water and are very sensitive to changing environmental conditions.  Population studies in the Arctic suggest that capelin migrate with temperature changes. During warm historical periods, capelin migrated through the Arctic Ocean to move between Pacific and Atlantic Oceans.  Strong preference for specific temperature regimes may cause some populations to become trapped in local refugia such as glacier fiords, if sea temperatures fluctuate.   Preliminary data in our laboratory suggests that the Bering Sea and Gulf of Alaska capelin populations are genetically isolated.  Based on their histories, we predict that capelin populations have strongly diverged in local refugia.  Understanding the genetic structure of Alaska capelin populations will allow us to estimate whether these populations are isolated and how they might respond to warming environmental conditions.  Results will provide crucial information to Gulf of Alaska and Bering Sea ecosystem models.

AFSC/RACE/SAP/Urban:Tanner Crab Handling  Mortality

Fish and invertebrates that are unintentionally captured during commercial fishing operations and then released back into the ocean suffer mortality at unknown rates, introducing uncertainty into the fishery management process. Attempts have been made to quantify discard mortality rates using reflex action mortality predictors or RAMP which use the presence or absence of a suite of reflexes to predict discard mortality. This method was applied to Tanner crab, Chionoecetes bairdi, during the 2010-2012 fisheries in the Bering Sea. Discard mortality in the fishery is currently assumed to be 50% in stock assessment models, but that rate is not based on empirical data and is widely recognized to be in need of refinement. Over 19,000 crab were evaluated using the RAMP method. The estimated discard mortality rate was 4.5% (SD = 0.812), significantly below the rate used in stock assessment models. Predicted discard mortality rates from the 2010-2012 study were strongly correlated with the air temperature at the St. Paul Island airport in the Pribilof Islands. Using this relationship the discard mortality rate from 1991-2011was estimated at 4.2% (SD = 1.08).

Aerial Survey Counts of Harbor Seals in Coastal Alaska (2003-2011)

This dataset supports efforts to estimate the abundance and trends in population size of Alaska harbor seals. Annual surveys of harbor seal populations are fundamental to estimation of seal abundance, distribution, and trends, which in turn are essential for stock assessment, conservation, and management. The most feasible approach to determining harbor seal distribution and abundance is to use aircraft to count seals when they haul out of the water and are visible. Harbor seals in Alaska occupy a geographically extensive range from approximately long. 172ÂºE to 130ÂºW (over 3,500 km east to west) and from lat. 51ÂºN to 61.5ÂºN (over 1,000 km north to south). Estimation of the abundance of harbor seals statewide requires broad-scale aerial surveys and these surveys have been conducted by NOAA Fisheries, the Alaska Department of Fish and Game, and other collaborators since the early 1980s. This dataset reflects counts of harbor seals from surveys conducted between 2003 and 2011. 

This dataset differs from earlier datasets in a few key areas: 1) records generally correspond to a count of the number of harbor seals within a single, geo-referenced digital photo, 2) photographs were not taken when no seals were present so additional analysis of survey effort and flight tracks was required to determine 0 counts.

AFSC/NMML/CCEP: Food habits of California sea lions in Washington, 1986 - 1999

From 1986 to 1999, The National Marine Mammal Laboratories' California Current Ecosystem Program (AFSC/NOAA) collected fecal samples and stomachs of male California sea lions from Washington. Scat samples were collected primarily from haulout sites in Puget Sound and a few were collected along the northern-outer Washington coast.  Stomach content samples were collected from dead/stranded California sea lions throughout Washington. The data contains prey identifications and analyses of samples including prey species composition, frequency of occurrence, and size of prey.

The broad scope of the Essential Fish Habitat (EFH) mandate requires an efficient process for describing and mapping the habitat needs of federally managed species.  For example, research indicates surficial sediments affect the distribution and abundance of many groundfish species, yet traditional sampling with grabs and cores is impractical over areas as large as the Bering Sea shelf.  Acoustic tools are suitable for large-scale surveying and show great promise as a substitute for direct-sampling methods, but they have not been proven useful for EFH purposes.

AFSC/RACE/SAP/Long: Data from: Habitat, predation, growth, and coexistence: Could interactions between juvenile red and blue king crabs limit blue king crab productivity?

This data set is from a series of laboratory experiments examining the interactions between red and blue king crabs and habitat.  We examined how density and predator presence affect habitat choice by red and blue king crabs.  Further experiments determined how temperature and habitat affect predation by year-1 red king crab on year-0 blue king crab.  Finally, long-term interaction experiments examined how habitat and density affected growth, survival, and intra-guild interactions between red and blue king crab.
