An archive of multi-frequency and multi-beam echosounder data (Simrad .raw format), collected as part of SWFSC-FRD surveys of the U.S. west coast between San Diego, CA and Vancouver Island, BC. The archive contains echo power and inerferometric-phase-angle data that describe acoustic backscatter from marine organisms ranging in size from zooplankton to fish.
Pelagic eggs collected using the CUFES during cruises conducted by the SWFSC Fisheries Resources Division from 1996 to present. Data are typically collected every 30 min while the ship is underway. Eggs are identified as Pacific sardine, northern anchovy, jack mackerel, hake, squid, or other fish eggs. Some additional species identifications have been noted in the comments.
This database contains icthyoplankton data collected as part of the California Cooperative Oceanic Fisheries Investigations (CalCOFI) program and other cruises designed to assess the status coastal pelagic species and the California Current ecosystem from 1951 to present. The primary data are eggs and larvae captured in ring or bongo nets (oblique tows), Calvet or paravet nets (vertical tows), and manta nets (surface tows).
