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.

Context

The CalCOFI data set represents the longest (1949-present) and most complete (more than 50,000 sampling stations) time series of oceanographic and larval fish data in the world. It includes abundance data on the larvae of over 250 species of fish; larval length frequency data and egg abundance data on key commercial species; and oceanographic and plankton data. The physical, chemical, and biological data collected at regular time and space intervals quickly became valuable for documenting climatic cycles in the California Current and a range of biological responses to them. CalCOFI research drew world attention to the biological response to the dramatic Pacific-warming event in 1957-58 and introduced the term “El Niño” into the scientific literature.

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. Data collected at depths down to 500 m include: temperature, salinity, oxygen, phosphate, silicate, nitrate and nitrite, chlorophyll, transmissometer, PAR, C14 primary productivity, phytoplankton biodiversity, zooplankton biomass, and zooplankton biodiversity.

Content

Each table has several dozen columns. Please see this page for the table details.

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.

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.

Bottle data collected during CalCOFI cruises 1601, 1604, 1607, and 16011, January 2016 - November 2016. 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 Oceanograhpy. 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.

Fish larvae counts and standardized counts for eggs 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 only tows where one or more larvae were captured for the species selected by the user, i.e., no "zero" tows. The "Larvae Counts" table includes all tows by species, i.e., both positive and negative tows.

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.

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.
