During the period 1987-2009 the Southwest Region (now West Coast Region) collected beach seine fish samples in the San Diego area in conjunction with eelgrass restoration projects. Data collected included location, species, length and number.
This dataset contains detections of acoustic tagged fish from two general locations: Golden Gate (east and west line) and Pt. Reyes. Several Vemco 69khz acoustic receivers were deployed at each of these general locations. The Golden Gate receivers were deployed beginning in April 2005 while the Pt Reyes receivers were deployed beginning in July 2008. The tagged fish in the dataset include all fish tagged by NOAA Santa Cruz and some green sturgeon tagged by NOAA in the Columbia River and Willapa Bay. Only a subset of these tagged fish were detected at the Golden Gate and Pt. Reyes. There are detections of many more fish that are not in the list of tagged fish in this dataset.
The project’s objective is to document movement patterns and survival rates of Chinook salmon, steelhead, green sturgeon, and other fish from several sources in the Central Valley of California. Juvenile salmonids from hatcheries or wild caught are implanted with small acoustic transmitters and the location of the fish are recorded on receivers that are placed throughout the watershed from Redding to the Golden Gate. Over 70 receiver locations with over 150 receivers monitor the movement of these fish. These receivers record the date, time, and unique identification number of transmitters that pass within listening range of the receivers. The first acoustic tagging studies began in 2006 and continue today.
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).
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. This file gives the legacy species codes assigned to each sighted fish group and their equivalent ITIS species codes. Each legacy species code may contain one and up to four species sighted in a group of fish spotted by the pilot in one block area during a flight.
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.
