title: California State Commercial Landings and CPFV Logbook Data

description: This data package include California state commercial fisheries landings and commercial passenger fishing vessel (CPFV) logbook data from the California Department of Fish and Wildlife (CDFW). The data contained in this data package were obtained under a non-disclosure agreement with the CDFW. Summaries of the commercial fisheries landings data and CPFV logbook data were developed in collaboration with CDFW staff using commercial landings receipt data and CPFV trip logbook data contained in the CDFW’s Commercial Fisheries Information System (CFIS) database. The non-disclosure agreement requires that all confidential CDFW data provided to the public be summarized so as not to disclose the individual record or business of any person. Following instructions from CDFW staff, all data points consisting of fewer than three commercial fishermen or CPFV operators were suppressed to protect individual information.

title: Commercial Fishing Data

description: The primary goal of this project was to inform long-term marine protected area (MPA) monitoring efforts by gathering up-to-date socioeconomic information to illustrate historical trends, establish a post MPA baseline, and assess initial changes since MPA implementation for the commercial fishing fleet in the North Coast region of California. To accomplish this goal our research team conducted extensive community outreach and engagement in the region and conducted in-person interviewed commercial fishermen to gather post MPA baseline socioeconomic data and spatial fishing data for the year 2013. Additional to the interview data gathered, we summarized commercial fishing landings data from 1992 to 2014 obtained from the California Department of Fish and Wildlife (CDFW) to explore historical economic trends and initial changes in North Coast commercial fisheries. This data package include the commercial fishing landings data from 1992-20142 provided by California Department of Fish and Wildlife summarized to the port and region level; select summarized survey data from fishermen interviews about their fishing operations in the 2013 calendar year, and samples of the spatial data available on the post MPA (2013) and spatial change between pre MPA (2000-2009) and post MPA (2012) fishing grounds at region-fishery and port-fishery scales.

title: ROV Tracking and Sensor Data

description: ROV surveys were conducted near and within MPAs along the California’s North Coast (from Crescent City to Fort Bragg). One second ROV location (Lat/Lon in WGS84) data of each transect line are provided. The ROV position was calculated using the relative location from the vessel’s GPS position by the navigation software (Hypack). The ROV was equipped with various oceanographic sensors and the data was directly recorded to the computer. CTD was also equipped on the ROV and the data was recorded separately by its own software (Sea-Bird). Transect files are included to lookup the Dive, Line, Site, date, beginning/ending times of each line and transect types. The position data was included to provide where the ROV went. The sensor and CTD data provide the oceanographic data of the location where the ROV was at each second.

title: Collaborative Fisheries Survey Data

description: To characterize the fish communities associated with nearshore rocky reef habitat, we collaborated with commercial passenger fishing vessel (CPFV) captains and volunteer anglers to conduct hook-and-line surveys in four pairs of MPA and reference sites. Sampling was conducted with scientific crews of six: four anglers, a sampler who handled, measured, and tagged fish, and a data recorder. Each of the four anglers used a different combination of baited or un-baited lures that represented gear frequently used by recreational anglers to catch the target species. Sites were sampled by fishing for 45 minutes in each of four 500 meter by 500 meter sampling cells, which were randomly selected from a set of cells that covered bottom areas containing at least 20 percent rocky reef habitat, by area. Captains were directed to drift within the cells over areas of rocky habitat for a maximum of 15 minutes per drift, so that at least three areas of habitat within each cell would be sampled. Captured fish were identified to species, measured to the nearest millimeter in fork length, tagged with an external t-bar anchor tag, and returned to the water, using a descending device if needed. Each site was sampled five times, three from June-October 2014, and twice from May-August 2015.

title: Collaborative size frequency surveys by commercial urchin divers

description: This metadata record documents the size frequency surveys for subtidal community surveys. Size frequency sampling consists of recording the number and size of target invertebrate species (urchins of the genus Strongylocentrotus and red abalone Haliotis rufescens). Individuals are encountered and recorded as separate swath surveys in the vicinity of the main swath survey site. Completed as part of a collaborative sampling by commercial urchin fisherman at a few select study sites in the summer of 2016. Subtidal community structure surveys are conducted annually at all sites during the summer or early fall, and quantify substrate type and relief, benthic cover, abundance of major groups of macroalgae and invertebrates, and abundance and size of fishes. Spatial allocation of sampling is designed to measure year-to-year site-wide variability in community structure and the spatial scales at which such variation occurs. A site is defined as a fixed area of coastline comprised of 3 cells, each occupying approximately 500m. Each cell is comprised of 4 benthic transects stratified across the two zones described below.

title: Biodiversity Point Contact Surveys

description: The Baseline surveys of rocky intertidal ecosystems (NC) project includes both Long-Term Monitoring and Biodiversity Surveys done in the North Coast of California. Long-Term Monitoring Surveys use fixed plots to document changes in percent cover, or abundance of targeted species or species assemblages. This fixed-plot approach allows the dynamics of rocky intertidal species to be monitored with reasonable sampling effort and provides sufficient statistical power to detect changes over space or time. Biodiversity Surveys provide detailed information about biodiversity and community structure. These surveys were designed to measure diversity and abundance of algae and invertebrates found within rocky intertidal communities on the western coast of temperate North America. This metadata record documents the Biodiversity Point Contact Surveys done as part of the NC Baseline surveys of rocky intertidal ecosystems. Biodiversity Point Contact sampling consists of recording the diversity and abundance of invertebrates and algae along 11 transects of variable length extending from the upper intertidal to the low intertidal. Biodiversity Surveys are comprised of three biological components, all sampled along the same transects: (1) point contact estimates of intertidal cover and substrate characteristics, (2) swath transects to estimate the density of sea stars and abalone, and (3) quadrat sampling to estimate the density of mobile invertebrates. Biodiversity Surveys are done throughout the year at sites ranging from Southeast Alaska to Baja California Sur, Mexico. Selected sites are resampled on a 3-5 year cycle. A site is defined as a contiguous rocky bench of at least 30m.

title: Motile Invertebrate Size Counts

description: The North Coast region's rocky intertidal habitat is home to an exceptional diversity of algae and invertebrates. The main objective of this project is to produce a baseline characterization of this important ecosystem in the region and compare sites inside and outside of MPAs. Researchers will document abundance, and distribution of invertebrates and algae, and will describe the rocky habitat (e.g., rock type and surface roughness). In addition, this project will generate a fish biodiversity baseline and monitor rockfish recruitment. Newly collected data will be analyzed in conjunction with existing Partnerships for Interdisciplinary Studies of Coastal Oceans (PISCO) data to identify potential indicator species of ecosystem health. This project is a collaboration among academic scientists and North Coast tribes. This package contains data on Motile Invertebrate size counts sampled within established plots of Mytilus californianus.
