The standard protocol consists of an observer visually estimating the amount of harvestable giant kelp biomass within designated kelp beds from a small fixed-wing aircraft. Observations were recorded on paper data sheets in the field and archived in notebooks housed at ISP Alginates. With cooperation from ISP Alginates, the SBCLTER converted ISP Alginates long-term records of giant kelp biomass into a digital format. The database consists of a data table containing kelp biomass, a catalog of maps. The format ISP Alginates used to report kelp abundance data changed periodically over the course of the collecting period. These details, pus descriptions of designated kelp beds are described in the protocol document. giant kelp biomass Macrocystis pyrifera Historical_kelp SBCLTER_Categories Users of data collected under the auspices of the SBC LTER are expected to adhere to the following conditions: (1) The user agrees to provide valid name and contact information to the SBC data manager prior to downloading online data.

Notes on data collection Beginning January 8, 1968, data on kelp biomass were occasionally reported on paper as the sum of multiple beds (e.g. a single value was reported for beds 2 and 3.) In such cases, the reported tonnage was split evenly among the combined beds in the digital version. prior to September 17, 1962, some of the bed designations used by ISP Alginates differed from those of the California Department of Fish and Game. Data recorded under these earlier ISP Alginates bed designations were entered into the database under the corresponding CDFG bed number. A conversion table of ISP Alginate bed numbers and CDFG bed numbers is shown below.

The standard protocol consists of an observer visually estimating the amount of harvestable giant kelp biomass within designated kelp beds from a small fixed-wing aircraft. Observations are recorded on paper data sheets in the field and archived in notebooks housed at ISP Alginates. With cooperation from ISP Alginates, SBC-LTER converted ISP Alginates long-term records of giant kelp biomass into a digital format. This document describes the organization of the Historical Kelp database and the methods that were used to create it. The format ISP Alginates used to report kelp abundance data changed periodically over the course of the collecting period. This document also describes the steps taken to standardize the historical records of kelp biomass into a consistent format.

Bed numbers in Central and Southern California were assigned by the California Department of Fish and Game; bed numbers in Baja region were assigned by ISP Alginates. Note that are some bed numbers were used in both the Southern and Baja regions, but refer to distinct beds in each region. A table of bed numbers and corresponding name, location, length of coastline encompassed by the bed, size, and description of the bed boundaries is shown in Table 1 of the protocol document.
