These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, nearshore monitoring component. Specifically, these data describe sea otter (Enhydra lutris) aerial survey observations from the waters around Katmai National Park and Preserve from surveys conducted in 2008, 2012, 2015, and 2018. Sea otters are a keystone predator, well known for structuring the nearshore marine ecosystem through their consumption of invertebrate prey. The dataset consists of 3 comma-delimited files (CSV) exported from Microsoft Excel. The data consists of (1) Strip transect counts, (2) Intensive Search Unit (ISU) counts, and (3) Transect coordinates. For each aerial survey, a pilot flew an airplane at an altitude...

This is a child item of the USGS Data Release: https://doi.org/10.5066/F7K072DR. This dataset includes zooplankton biomass from Prince William Sound, Icy Bay and Yakutat Bay, Alaska. Zooplankton were sampled with a ring net (0.6 m diameter with 211 µ mesh) on a 50 m vertical haul or to within 5 m of the bottom in shallow water. Zooplankton samples were identified to species and life stage when possible.
This is a child item of the USGS Data Release: https://doi.org/10.5066/F7K072DR. This dataset contains catch data from trawls at the sampling stations. We deployed a modified herring trawl in coastal waters within glacier fjords of Alaska. Sampling stations in each fjord were chosen randomly from a 2.5 x 2.5 km grid overlaid on navigable waters in the fjord. The number of stations in each fjord was chosen to achieve a sampling frequency of about 1 sample per 15 km^2, and was based on available resources and logistical constraints (weather, navigational hazards and vessel time).

This is a child item of the USGS Data Release: https://doi.org/10.5066/F7K072DR. This dataset contains physical oceanographic data within four fjords in the coastal area of the Gulf of Alaska. Data were collected with a Seabird Electronics conductivity-temperature-depth profiler equipped with external sensors and a water sampler. Glacier runoff provides a link between terrestrial systems and nearshore coastal processes, whereby freshwater input influences the physical oceanographic properties and circulation of fjords (Arimitsu et al. 2016).

This is a child item of the USGS Data Release: https://doi.org/10.5066/F7K072DR. These data describe marine bird and mammal surveys conducted in glacial fjords of coastal Alaska. Data were collected to document the at-sea distribution and abundance of marine birds and mammals in Glacier Bay National Park (2004), Prince William Sound (2010), Icy Bay (2011) and Yakutat Bay (2011). Following standard US Fish and Wildlife protocols for strip surveys.
This is a child item of the USGS Data Release: https://doi.org/10.5066/F7K072DR. This dataset includes zooplankton displacement volume sampled in Glacier Bay National Park during summer of 2004. Zooplankton were sampled with a multinet with a 0.5 m^2 mouth opening and 335 µ mesh.
This is a child item of the USGS Data Release: https://doi.org/10.5066/F7K072DR. In order to understand marine ecosystem responses to a range of habitat variability in coastal zones modified by glacial freshwater outflows, biophysical data were collected in three study regions that included four major glacial fjord systems around the Gulf of Alaska. Each of 172 discrete stations within the three study regions was sampled once during the peak ice-melt season in summer. A suite of geographic, oceanographic, nutrient and biological attributes was sampled at each station (see Arimitsu et al. 2008, Renner et al. 2012, Arimitsu et al. 2016 for details). This dataset includes station information, including date, time,...
These data are is part of the Gulf Watch Alaska (GWA) long term monitoring program, nearshore monitoring component. Specifically, these data describe sea otter (Enhydra lutris) aerial survey observations from the waters around Kenai Fjords National Park between 2002 and 2016. Sea otters are a keystone predator, well known for structuring the nearshore marine ecosystem through their consumption of invertebrate prey. The dataset consists of 3 comma delimited files exported from Microsoft Excel. The data consists of 1. Strip transect counts, 2. Intensive Search Unit (ISU) counts, and 3. Transect coordinates. For each aerial survey, a pilot flew an airplane at an altitude of 91m over pre-determined transects while an...
This volume's release consists of 15184 media files captured by autonomous wildlife monitoring devices under the project, Bureau of Land Management Riverside East Solar Energy Zone. The attached files listed below include several CSV files that provide information about the data release. The file, "media.csv" provides the metadata about the media, such as filename and date/time of capture. The actual media files are housed within folders under the volume's "child items" as compressed files. A critical CSV file is "dictionary.csv", which describes each CSV file, including field names, data types, descriptions, and the relationship of each field to fields in other CSV files. Some of the media files may have been "tagged"...
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set includes mosaicked aerial photographs for the Cameron-Creole Maintenance (CS-04a) project for 2021. This data is used as a basemap land-water classification. It also serves as a visual tool for project managers to help them identify any obvious problems or land loss within their project...

This data set includes capture location, date, sex, and results of molecular gene transcription analysis for sea otters (Enhydra lutris) sampled in western Prince William Sound (WPWS), Alaska and comparison samples collected from Kodiak and the Alaska Peninsula, and reference samples collected from captive animals. Samples were collected between 2005 and 2012. Molecular gene transcription is the process by which information from the DNA template of a particular gene is transcribed into messenger RNA (mRNA) and eventually translated into a functional protein. The amount of mRNA transcribed from a particular gene is physiologically dictated. Altered levels of gene transcripts provide observable signs of health impairment.

This is a child item of the USGS Data Release: https://doi.org/10.5066/F7K072DR. This dataset contains nutrient data collected at stations within four fjords in the coastal area of the Gulf of Alaska. Sea water samples were collected with a Seabird Electronics Ecosampler SBE55 attached to a conductivity-temperature-depth profiler. Bottles were fired at the surface (0 m) and from 8 m (in Glacier Bay, AK in 2004) or 10 m (in Prince William Sound, AK in 2010 and in Icy Bay and Yakutat Bay, AK in 2011). Samples were processed for nitrite (NO2), nitrate (NO3), ammonium (NH4), phosphate (PO4), and silicic acid (SIOH4).
