An aerial monitoring program was conducted during the period 1962 - 2007 in cooperation with aerial spotters working for the commercial purse seine fleet. Flights were conducted throughout the year to estimate abundance of pelagic fishes off California and Baja California, Mexico. Measurements were recorded for each identifiable species in 10'-longitude by 10'-latitude blocks. Each record in this file describes the date, time of the day, location, total tonnage and/or number of schools sighted for some species by a pilot on a flight in a 24-hour period.
Scientists from NOAA Fisheries Service's Benthic Resources Group and NOAA Center for Coastal Environmental Health and Biomolecular Research participated in a six-day (November 1-6, 2010) research cruise aboard NOAA's newest Fisheries Survey Vessel (FSV), the Bell M. Shimada , to investigate deep-water sponges and corals between San Diego, CA and Seattle, WA. Remotely operated vehicle (ROV) surveys were conducted in Sur Canyon, south of Monterey Bay; on The Football, a bank north of San Francisco Bay; on Coquille Bank off the OR coast, and two sites within the Olympic Coast National Marine Sanctuary (OCNMS).
Weight in kilograms for all species (identified to lowest taxonomic criteria) caught during SWFSC-FRD fishery independent surveys (including DEPM, ATM, SaKe) of coastal pelagic species using mid-water trawls (with most tows performed near the surface) at position and times listed. Additional information for a subset of individuals from some species can be found in either CPS Trawl Life History Length Frequency or the CPS Trawl Life History Specimen datasets.
At-sea distribution and density of marine mammals and seabirds. Seabird and marine mammal observations were collected from research vessels during transits between stations, to and from port of calls, etc.
Egg morphological developmental stage for eggs of selected species captured in CalCOFI icthyoplankton nets. Sequential developmental stages are described by Moser and Ahlstrom (1985; see the info url references section).
We aerially surveyed leopard seals of known body size and mass to test the precision and accuracy of photogrammetry from a small UAS. Flights were conducted in January and February of 2013 and 2014 and 50 photogrammetric samples were obtained from 15 unrestrained seals. Photogrammetric measurements from a single, vertical image obtained using UAS provide a noninvasive approach for estimating the mass and body condition of pinnipeds that may be widely applicable.
Fish captured in trawls by the SWFSC Fisheries Resources Division during surveys for coastal pelagic species. Most tows were targeted for sardine using a Nordic trawl on the surface at night. The database includes identification to various taxonomic levels depending on species, length frequencies, biomass data, and some age data for sardine based on analysis of otoliths.
This project was part of a larger international project (SPLASH) designed to estimate the abundance and determine the population structure for humpback whales throughout the North Pacific involving the governments of Canada and Mexico as well as multiple agencies within the government of the U.S. The primary study methods were photo-identification and biopsy sampling. Passive acoustics were used to aid in finding aggregations of whales. In addition, biological and oceanographic data were collected to better characterize the whale’s environment, and survey data were collected for all other cetacean and pinniped species observed. Biopsy samples were also taken from other cetacean species, primarily in areas where they have been poorly sampled in the past. The Hawaiian Island Humpback Whale Sanctuary (HIHWS) collaborated on this cruise by sending two skilled photographers on each leg of survey effort. The U.S. Navy collaborated on this cruise by funding the acoustic and oceanographic sampling.
Fish larvae counts and standardized counts for larvae captured in CalCOFI icthyoplankton nets (primarily vertical [Calvet or Pairovet], oblique [bongo or ring nets], and surface tows [Manta nets]). Surface tows are normally standardized to count per 1,000 m3 strained. Oblique tows are normally standardized to count per 10 m2 of surface sampled. This table includes all tows by species, even if zero larvae were captured for the species, i.e., negative tows. The "Larvae Counts Positive Tows" table includes only tows where one or more larvae were captured for the species selected by the user.
