This data is part of the Gulf Watch Alaska (GWA) long term monitoring program, nearshore monitoring component. The data consists of date, time, and temperature measurements from intertidal rocky sampling sites. The dataset is 5 comma separated files exported from a download from the HOBO temperature logger. Sites are in Alaska and include locations in Katmai National Park and Preserve, Kenai Fjords National Park and northern and western Prince William Sound. There are five sites in each of those areas. The time interval includes 2014-2016. Temperature loggers were set to record hourly. Each file is comprised of data from a single site from a given year. Loggers were re-used so the logger serial number is included...

Subaerial landslides at the head of Barry Arm Fjord in southern Alaska could generate tsunamis (if they rapidly failed into the Fjord) and are therefore a potential threat to people, marine interests, and infrastructure throughout the Prince William Sound region. Knowledge of ongoing landslide movement is essential to understanding the threat posed by the landslides. Because of the landslides' remote location, field-based ground monitoring is challenging. Alternatively, periodic acquisition and interferometric processing of satellite-based synthetic aperture radar data provide an accurate means to remotely monitor landslide movement. Interferometric synthetic aperture radar (InSAR) uses two Synthetic Aperture...

This service shows the Environmental Sensitivity Index (ESI) developed for Price William Sound, AK, in 2000. Both linear and polygonal shoreline features are included here. Associated GIS datasets can be downloaded here.ESI maps use shoreline rankings to rate how sensitive an area of shoreline would be to an oil spill. The ranking scale goes from 1 to 10.A rank of 1 represents shorelines with the least susceptibility to damage by oiling. Examples include steep, exposed rocky cliffs and banks. The oil cannot penetrate into the rock and will be washed off quickly by the waves and tides.A rank of 10 represents shorelines most likely to be damaged by oiling. Examples include protected, vegetated wetlands, such...

Marine mussels are a ubiquitous and crucial component of the nearshore environment, and new genomic technologies exist to quantify molecular responses of individual mussels to stimuli, including exposure to polycyclic aromatic hydrocarbons (PAHs). We used gene-based assays of exposure and physiological function to assess lingering oil damage from the 1989 Exxon Valdez oil spill using the Pacific blue mussel, Mytilus trossulus. We developed a diagnostic gene transcription panel to investigate exposure to PAHs and other contaminants and their effects on mussel physiology and health. Mussels were collected annually from 2012 through 2015 at five field sites (mussel beds) in western Prince William Sound: Herring Bay,...
The data consist of blood chemistry and hematology from sea otters captured at sites along the Aleutian archipelago, the Alaska Peninsula, the Gulf of Alaska, and Prince William sound between 2004 and 2012. The data include the blood chemistry and hematology findings as well as general capture location, if the sea otter population in that area is declining, capture date, age estimate, age class, sex, and a unique sea otter number connecting the sample to gene expression data.

This data is part of the GulfWatch Alaska (GWA) long term monitoring program, benthic monitoring component. The data consists of date, time, and temperature measurements from intertidal rocky sampling sites. The site name is part of the file name. The dataset is several comma separated files exported from a download from the HOBO temperature logger. Sites are in Alaska and include locations in Katmai National Park and Preserve, Kenai Fjords National Park and eastern, northern, and western Prince William Sound. There are five sites in each of those areas. The time interval includes 2006-2015. As the temperature logging protocol was developed different monitoring intervals were used. Most temperature loggers were...
Three data sets are included here to aid in assessment of the sea otter population collapse in southwest Alaska. One data set consists of results of sea otter surveys conducted between 1959 and 2015 at Bering Island, Russia and a selection of western Aleutian Islands in Alaska. Sea otter counts are reduced to a comparable value of otters per linear kilometer. Another data set consists per-capita and per kilometer recovery rates of stranded sea otter carcasses from locations ranging from Bering Island, Russia, several Aleutian Islands, sites along the Alaska Peninsula, and Prince William Sound, Alaska. These data are mainly from the period 1991-2009 and are from stable populations as well as those in decline or post...

This data set comprises the Environmental Sensitivity Index (ESI) data forPrince William Sound, Alaska. ESI data characterize estuarine environmentsand wildlife by their sensitivity to spilled oil. The ESI data includeinformation for three main components: shoreline habitats, sensitivebiological resources, and human-use resources. This data set contains theEnvironmental Sensitivity Index shoreline data.

High-resolution single channel minisparker seismic-reflection data were collected by the U.S. Geological Survey and the Alaska Department of Fish and Game in May 2014 in southern Prince William Sound southwest of Chenega and from southwest of Montague Island, Alaska. Data were collected aboard the Alaska Department of Fish and Game vessel, R/V Solstice, during field activity 2014-622-FA, using a 500 Joule SIG 2-mille minisparker sound source and a single channel streamer and recorded with a Triton SB-Logger.
