Abstract:
In spring 1991, Southeast Alaska, Cook Inlet, and Bristol Bay, was surveyed for harbor porpoise (&lt;i&gt;Phocoena phocoena&lt;/i&gt;) from the NOAA John N. Cobb using line transect methodology. The shipboard platform was 28.36 m (93 ft) in length with a bridge height of 4.27 m (14 ft). To obtain data on seasonal movements of porpoise, a limited number of transects were made in areas of known porpoise concentrations. When a sighting was made, the following variables were recorded: time, angle, number of reticles to the sighting, radar distance (nm) to the shoreline at the same angle of the sighting, the species, the count of the porpoise seen (best, high, and low), and the animal(s) direction of travel. Search effort was recoded by noting the time and location of the ship at the beginning and end of each transect.

Aerial surveys of marine birds have been conducted annually since 1992 by the Puget Sound Ambient Monitoring Program (PSAMP) staff during both a summer (July) and a winter (December to early February) survey window, sampling some part of every portion of the marine shoreline of the inner marine waters of Washington state by two strata: nearshore (&lt;20 meters in depth) and offshore (&gt;20 meters in depth).

The datasets are split by season (summer or winter) and year. The nearshore strata were sampled in two fashions:&lt;br&gt;
1) In nearshore habitat that was relatively narrow, the plane flew parallel to the shoreline generally 100 meters from the high tide line;
2) In nearshore habitat with broad extensive shallow areas such as river estuaries, the plane flew in an S-pattern to sample a larger proportion of the habitat available in that locality.
The offshore strata were sampled in a crisscross pattern that zigzagged back and forth across depth contours, with an attempt made to cut across most all banks and similar major underwater bathymetric features. There was no attempt made to survey during the same tidal stage in these areas.

The survey always began in the southernmost study areas and proceeded to the northern portions; therefore the same areas were usually sampled during the same time of month each year, give or take a week. The last two summer surveys (1997-1998) did not include the southern and central portions of Puget Sound, due to budget cuts. These areas were chosen to be continued on a less frequent basis because low and consistent numbers of birds were seen there during the July survey window in the previous five summer surveys.

Abstract:
In spring 1992, Southeast Alaska, the south side of the Alaskan Peninsula, and the Kodiak Archipelago were surveyed for harbor porpoise (&lt;i&gt;Phocoena phocoena&lt;/i&gt;) from the NOAA John N.

Abstract:
The Biological Investigations of Marine Antarctic Systems and Stocks (BIOMASS) Programme was established in the late 1970's for the study of the Antarctic marine ecosystem and its living resources (Thorley, online resource). Data were collected during 3 major field experiments between 1981 and 1985, divided into two periods: First International BIOMASS Experiment (FIBEX) in 1980-1981, and the Second International BIOMASS Experiment (SIBEX) in 1983-1985.
In total 34 cruises were carried out (El-Sayed, online resource), of which 21 cruises were gathered in this data set. This data set provides sea-bird observation collected in the cruises.

Abstract:
This dataset is from the Oregon and Washington marine mammal and seabird surveys studies: Oregon/Washington ship [bird and mammal observations] study code: MF, Contract number: 14-12-0001-30426, Principal investigators: G. A. Green, Ebasco Environmental, Bellevue, Washington, M. L. Bonnell and K. T. Briggs, Ecological Consulting, Inc., Portland, Oregon.

Time period: April 1989 through October 1990

Study area: Pacific Ocean waters of Oregon and Washington from the coast to approximately 60 nautical miles offshore.

Methodology: Aerial surveys were conducted along 32 pre-established transects designed to systematically sample marine mammal and seabird abundance in all waters of the study area. Coastal surveys and one shelf break survey were also conducted. Standard transects provided systematic coverage of shelf, slope, and offshore waters in the study area. Sightings of seabirds, pinnipeds, cetaceans, and turtles were recorded. Seabird sightings were recorded only on the shaded side of the aircraft within a strip transect of 50 m width. Marine mammal and turtle sightings were recorded within an unbounded corridor. Declination angle was measured and noted for each marine mammal/turtle sightings and later used to calculate a probability density function of frequency with right-angle sighting distance. Navigation was by Loran and VLF-Omega. One ship survey was also conducted from aboard the NOAA ship Miller Freeman during August 1989.
Databases produced: 1) sightings of seabirds and marine mammals on 12 aerial surveys and one ship cruise, and 2) sightings of cetaceans on 12 aerial surveys and one ship cruise.

Abstract:
This dataset is from the marine mammal and seabird surveys of central and northern California studies: Central/northern California - low aerial [birds and mammals] study code: CL, Contract number: 14-12-0001-29090, Principal investigator: Thomas P. Dohl, Center for Marine Studies, University of California, Santa Cruz

Time period: February 1980 through June 1983
Study area: Shelf, slope, and offshore waters to a distance of 100 nm off the California coast from Point Conception to the California-Oregon boundary.

Methodology: Offshore transect surveys were flown twice-monthly at two different altitudes (200 ft and about 750-1,000 ft ASL) along approximately 40 east-west transect lines extending an average of 60 nm offshore. The transects sampled on a given survey were selected randomly from a set of 92 standard (predetermined) lines spaced at intervals of 5’ of latitude. Standard transects provided systematic coverage of shelf, slope, and offshore waters in the study area. Sightings of seabirds, pinnipeds, and sea otters were recorded only on low-altitude surveys. Sightings of cetaceans and turtles were recorded on both low- and high-altitude surveys. Seabird sightings were recorded only on the shaded side of the aircraft within a strip transect of 50 m width. Marine mammal and turtle sightings were recorded within an unbounded corridor on both high- and low-altitude surveys, but only the shaded side of the aircraft was searched on the low-altitude surveys. Cross-legs connecting standard transects were searched only on high-altitude surveys. Offshore cross-legs were searched on both sides of the aircraft, while only the nearshore side was searched on cross-legs along the coast. Declination angle was measured and noted for each marine mammal/turtle sightings and later used to calculate a probability density function of frequency with right-angle sighting distance. Navigation was by Loran and VLF-Omega.

Databases produced: Three databases of sightings at sea were produced by these studies (data on numbers of seabirds and pinnipeds on land were also collected but are not addressed in the present study). These include: 1) sightings of cetaceans and turtles recorded on 36 high-altitude aerial surveys, 2) sightings of cetaceans, pinnipeds, sea otters, and turtles recorded on 36 low-altitude aerial surveys, and 3) sightings of seabirds on 36 low-altitude aerial surveys. Each sighting database is accompanied by files providing the search effort on transect and environmental characteristics of the waters surveyed (e.g., sea surface temperature).

Abstract:
On 15 August 1991, as part of a larger study, Alaska harbor porpoise (&lt;i&gt;Phocoena phocoena&lt;/i&gt;) abundance was investigated during an aerial survey of waters off southeastern Alaska. A Twin Otter was used to fly a single sawtooth trackline at an altitude of 152.2 m (500 ft) and at an airspeed of 185 km/h. Line-transect methodology was used, and only those observations made during optimal conditions were analyzed. Density of harbor porpoises was calculated using line transect estimates based on perpendicular distances of sightings to the cruise track of the airplane.
