This database contains ichthyoplankton data collected as part of the California Cooperative Oceanic Fisheries Investigations (CalCOFI) program and other cruises that were 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 pairovet nets (vertical tows), and manta nets (surface tows).

The California Cooperative Oceanic Fisheries Investigations (CalCOFI)

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.

In 1951, the Hopkins Marine Station of Stanford University became involved in the California Cooperative Oceanic Fisheries Investigations (CalCOFI) program to collect oceanographic data in and near Monterey Bay. Hopkins staff conducted weekly sampling (more or less) continuously from March 1951 through June 1974. Moss Landing Marine Laboratories (MLML) took over the Monterey Bay sampling program in July 1974, and it appears to have ended in 1979. The aim of the initial program was to conduct joint fisheries-oceanographic cruises that would help researchers understand what contributed to the crash of the California sardine fishery. The Hopkins Marine Station CalCOFI dataset is an extremely important contribution to early oceanographic research in the Northeast Pacific Ocean, and extends our observations in this area decades into the past. The raw and aggregated data for most of these cruises currently resides in the library at the Hopkins Marine Station. This portion of the dataset is a transcription of the zooplankton data that was collected from 1955 to 1963 (a subset of the full HMS CalCOFI program). These spreadsheets are the output of a crowdsourcing campaign on the 'From the Page' platform. We thank 58 contributors for transcribing over 1500 pages! See the dataset README file for detailed information about the data.

Abstract: From July 2004 to April 2008 dedicated visual observers following consistent line-transect methods (Buckland et al., 1993; Kinzey et al., 2003) observed from the CalCOFI platforms on quarterly cruises. Observers used handheld 7X50 reticle Fujinon binoculars to sight, identify, and make school size estimates of cetaceans and pinnipeds encountered along the transect lines between CalCOFI water sampling stations. The southern water sampling stations are set along six, parallel lines running southwest to northeast, with lines increasing in length from north to south (470 – 700 km) and stations occurring every 37 km in coastal and continental shelf waters and every 74 km offshore. Three research vessels were used for the sixteen surveys, Scripps Institution of Oceanography Roger Revelle (2 surveys) and New Horizon (8 surveys) and, NOAA David Starr Jordan (6 surveys), vessel height varied from 8.1-13.2m and survey speed varied from 10 to 12 knots.

Purpose: The waters off southern California are remarkably diverse and species rich, but they are also an area of swift commercial development, navy training activity, population growth and climate change. Continued visual marine mammal and seabird surveys working in concert with oceanographic ecosystem investigations are essential for monitoring the health and changes of the California current system.

Abstract: This dataset contains observation data of marine birds and mammals from California Cooperative Oceanic Fisheries Investigations (CalCOFI) from 1987-2006 and Rockfish cruises along the California coast from 1996-2006 by National Marine Fisheries Service (NMFS).

Data were collected aboard research vessels using standardized marine bird and mammal survey techniques (Tasker et al. 1984, Buckland et al. 1993). Marine birds and mammals were observed in a 90-degree arc from the bow to one side of the ship out to 300m. Counts are summarized by species and behavior along the transects in 3 km bins. Data span years 1987 - 2006.

This collection includes data collected from multiple platforms in the coastal waters of California over many years, as part of the California Cooperative Fisheries Investigation (CalCOFI) project. CalCOFI has been observing the California Current since 1949 to understand and predict the effects of climate change on marine ecosystems. This collection includes physical measurements and observations of temperature, conductivity, pressure, salinity, density, sound velocity, sigma-t, depth, humidity, photosynthetic active radiation (PAR), light transmission, turbidity, solids, water color, tide, current, sea, swell, wave, weather, wind, cloud, chemical measurements and observations of alkalinity, ammonia (NH3), ammonium (NH4), nitrate, nitrite, nitrogen, carbon, oxygen, pH, phosphate, phosphorus, polychlorinated biphenyls, silicate, urea, biological measurements and observations of chlorophyll, productivity, fluorescence, phaeophytin, phaeopigment, phytoplankton, zooplankton, as well as fishery surveys and other data.

Bottle data collected during CalCOFI cruises 1203, 1207, 1210, and 1301, March 2012 - January 2013. The California Cooperative Oceanic Fisheries Investigations (CalCOFI) are a unique partnership of the California Department of Fish & Wildlife, NOAA Fisheries Service and Scripps Institution of Oceanography. The organization was formed in 1949 to study the ecological aspects of the sardine population collapse off California. Today our focus has shifted to the study of the marine environment off the coast of California, the management of its living resources, and monitoring the indicators of El Nino and climate change. CalCOFI conducts quarterly cruises off southern & central California, collecting a suite of hydrographic and biological data on station and underway.

The fish larvae (ichthyoplankton) survey is conducted through the California Cooperative Fisheries Investigations program (CALCOFI, http://www.calcofi.org/). These data are a time series of fish larvae counts (or density, as number per 10 m2 of ocean surface) collected in the area of the California Current between San Diego and Avila Beach, California, during the period of 1966 to 2015. Original data were filtered to facilitate consistent comparisons over time and space.

The original CalCOFI fish larvae count data is available from the CoastWatch West Coast Regional Node (WCRN) at NOAA’s Pacific Fisheries Environmental Laboratory, http://coastwatch.pfeg.noaa.gov/erddap/tabledap/index.html. The dataset presented here is an aggregation of 31 data files, originally divided alphabetically by taxon (named “CalCOFI Larvae Counts, Scientific Names * to *”). The data were filtered to include only the 66 core stations with a maximum of 1 cruise per season. These 66 core stations have been most frequently sampled in the past and sampling is ongoing.

CalCOFI sampling began in 1949. However, the dataset presented here begins in 1966 to include only samples that were analyzed with techniques that apply the most current and accurate identification of larvae to the species level. As the backlog of samples (i.e., before 1966) is re-examined, this dataset will be augmented with that additional, earlier data.

The data included in this dataset are bird and mammal observations from aboard research cruises. There are six tables of data: a transect log and observation log pairing for each of the three types of cruises. California Cooperative Oceanic Fisheries Investigations (CalCOFI) cruises are conducted quarterly off the coast of southern and central California. National Marine Fisheries (NMFS) cruises are a part of the Rockfish Recruitment Survey off the coast of southern and central California. Data were also collected aboard North Pacific Continuous Plankton Recorder (NPCPR) cruises from June 2002 through May 2006. Observations of birds and mammals include both number and behavior in addition to temporal and spatial information recorded along the cruise transect. Data are collected in order to research the interdependent aspects of the marine environment, including the effects of natural and human based climate change, and the broad implications and influences of ocean currents, weather patterns, fishing practices and coastal development on marine food webs and ecosystem processes.

Species and behavior definitions for data codes are available in the "Supplemental Documents" section.
