The North Atlantic Right Whale Aerial Survey is a NOAA Fisheries program conducted by the Northeast Fisheries Science Center, which conducts aerial surveys to locate and record the seasonal distribution of North Atlantic Right Whales (Eubalaena glacialis) off the northeastern coast of the United States. The purpose of these North Atlantic Right Whale (NARW) aerial surveys is to monitor the population, track injury rates, and identify areas of entanglement and vessel collision risks. The Marine Mammal Protection Act (MMPA) and Endangered Species Act (ESA) mandates the National Marine Fisheries Service (NMFS) to evaluate the status of the NARW population and reduce mortality below the population's Potential Biological Removal (PBR) in order for the species to recover. A major component of the surveys is photo identification of individual right whales to estimate the population and its annual rate of mortality. Distance sampling data is collected for all large whale species during systematic aerial surveys of neritic waters of the eastern seaboard of the U.S. Additional aerial surveys are focused in areas of seasonal right whale occurrence. Right whale absolute density (individuals km2) is calculated from spatial, temporal, and environmental covariates, accounting for detectability differences between observation conditions, and corrected for perception and availability biases, whale dive behavior, group composition, and group size. Seasonal densities are calculated using covariate maps. When right whales are encountered, the aircraft breaks from the systematic trackline to circle and collect photographs of natural markings on the whales for individual identification using handheld digital cameras. Estimation of the NARW population is based on a state-space model of the sighting histories of individual whales constructed from the central photo-ID catalog curated at the New England Aquarium. Most of the population is photographically captured each year. The comprehensive capture effort provides small credible intervals to the population estimate, which in turn provides relatively precise estimates of annual mortality. High precision estimates of right whale mortality are critical to meet conservation goals. Photographic captures in specific areas over shorter periods can provide estimates of both local abundance and seasonal residency of individuals.

The Right Whale Sighting Advisory System (RWSAS) is a NOAA Fisheries program which was designed to reduce collisions between ships and the critically endangered North Atlantic right whale (Eubalaena glacialis) by alerting mariners to the presence of the right whales. These reports are obtained from a variety of sources including aerial surveys, shipboard surveys, whale watch vessels, and opportunistic sources (Coast Guard, commercial ships, fishing vessels, and the general public).

As part of an inter-agency agreement between the National Marine Mammal Laboratory and the Bureau of Ocean Energy Management, aerial surveys of the North Aleutian Basin and sourtheastern Bering Sea were conducted from 24 July to 28 August 2008 and 14 July to 25 August 2009. Both surveys were conducted from an Aerocommander 690A. In 2008, the survey design consisted of broadscale transects covering the waters from Bristol Bay west to the Pribilof Islands. The survey covered a total of 5,821 nmi (10,782 km) on-effort, 471 nmi (872 km) transit and crosslegs, and off-effort accounted for 837 nmi (1551 km). There were a total of 263 sightings (755 individuals) of 11 confirmed marine mammals species; these included right, humpback, fin and sei whales as well as killer whales, Dall's, and harbor porpoise, Pacific white-sided dolphins, fur seals, sea lions, walrus and sea otters. There were 10 sightings (12 individulas) of right whales recorded on 3 separate days. Six unique individuals were photo-identified and 4 matches were made between the aerial and vessel surveys. In 2009, the survey consisted of finescale transects over the critical habitat and an acoustic component was added to complement the visual survey. The survey covered a total of 2,590 nmi (4,800 km) on effort . There were a total of 124 sightings (213 individuals) of 3 confirmed marine mammal species, right, humpback and fin whales. There were 23 sightings (28 individuals) of right whales documented on 9 separate days. Seven unique individuals were photo-identified. Three matches were made to the 2008 survey. In all, the 2 year survey documented 10 unique North Pacific right whales.

These data represent Seasonal Mangagement Area locations where regulations implement speed restrictions in shipping areas at certain times of the year along the coast of the U.S. Atlantic seaboard. The purpose of the regulations is to reduce the likelihood of deaths and serious injuries to endangered North Atlantic right whales that result from collisions with ships as designated by 73 FR 60173, October 10, 2008, Rules and Regulations.

This dataset contains ARGOS location data (latitude and longitude in decimal format) and associated time (date and time) and location quality (as defined by Argos System, www.argos-system.org) information. Data were collected using Wildlife Computers PTT-only SPOT 5 satellite transmitters and PTT identification is also provided with the data. Satellite transmitters were deployed on North Pacific right whales (Eubalaena japonica) in the eastern Bering Sea. This project was funded by the North Pacific Research Board (http://www.nprb.org/).

The North Pacific right whale (NPRW) was heavily hunted between the 17th and the 20th centuries. Protection was supposedly afforded by international treaties in the 1930s and 1940s, but the illegal capture of hundreds of individuals by the Soviet Union, primarily in the 1960s drastically impacted the recovery of the species. Currently, only a small remnant of this population (estimated at approximately 30 individuals) inhabits the southeastern Bering Sea (SEBS). There is an increasing body of evidence suggesting that the middle shelf domain constitutes the primary habitat of NPRWs in the SEBS during the summer. Despite substantial observation effort from various sources in some other areas, the only region in the Bering Sea where NPRWs have been consistently seen is the middle shelf. Vessel surveys were conducted in the summers of 2007 - 2011 in the EBS mostly within the NPRW critical habitat boundary (located on the middle shelf of the SEBS). A total of eight NPRW individuals were identified from photographs taken during the survey.

The National Marine Fisheries Service (NMFS) has conducted shore-based counts of the Eastern North Pacific stock of gray whales (Eschrichtius robustus) 26 years from 1967 to 2008 at Granite Canyon (or nearby at Yankee Point), 13 km south of Carmel, in central California. Convenient access to the Granite Canyon research station (owned by NOAA but operated by the State of California Department of Fish and Game) and the narrowness of the whales' migratory corridor in this area permitted an efficient counting process at this site. All counts were conducted during the 2-month southbound migration (mid-December to late February) rather than the protracted 3-month northbound migration. The routine nature of these counts and the consistency in research protocol lend themselves to inter-annual trend analyses. Research protocol has been based on single observers independently searching for whales and recording data on environmental conditions and the time, location, count, and direction of travel for each sighting. The counting system and observer performance has been tested through paired, independent observational effort; aerial surveys; thermal imagery; radio-tagging of whales; systematic observations through high-powered (25x) binoculars; and teams of observers tracking specific whale pods through the viewing area.

Annual telemetry data are collected as part of specific projects (assessments within watersheds) or as opportunistic efforts to characterize Atlantic salmon smolt migration dynamics. Telemtry projects have since expanded to include the tracking of a variety of non-Atlantic salmon species.
