Pacific Reef Assessment and Monitoring Program: Rapid Ecological Assessments of Fish Belt Transect Surveys (BLT) at Coral Reef Sites across the Pacific Ocean from 2000 to 2009

Description

Belt transects (BLT) is one of the non-invasive underwater-survey methods to enumerate the diverse components of diurnally active shallow-water reef fish assemblages. At each REA survey sites, BLT fish surveys are conducted along 3 consecutively-placed, 25m transect lines to quantify relatively small-bodied and abundant fishes. A pair of scuba diver-observers conducts parallel swims along the transect lines, recording size-class specific counts of all fishes encountered, to species-level where possible, within visually estimated but defined belt widths: 4 m wide for fishes > 20 cm TL (100 m2 area) on the initial swim-out, and 2 m wide for fishes < 20 cm TL (50 m2 area) on the subsequent swim back. Transects lines are typically set at depths of 10-15 m. Reef ledges and holes are visually searched. Stations are completed on all sides of the island/atoll, weather and sea conditions permitting. Raw survey data included species level abundance estimates.

Reef fish and benthic estimate data collected during BLT surveys can be accessed online via the NOAA National Centers for Environmental Information (NCEI) Ocean Archive.

DOI: 10.15468/tzr5bf OBIS Dataset ID: a54a77db-7b42-4101-8d71-1adec3dd4ed5 OBIS provides a portal or gateway to many datasets containing information on where and when marine species have been recorded. The datasets are integrated so you can search them all seamlessly by species name, higher taxonomic level, geographic area, depth, and time; and then map and find environmental data related to the locations. There are several ways to access OBIS data: (1) Mapper, (2) API, and (3) R package. The mapper allows you to visualize and inspect subsets of OBIS data. A variety of filters (taxonomic, geographic, time, data quality) is available and multiple layers can be combined in a single view. Layers can be downloaded as CSV files. Developers can access data through the OBIS API or the R package. Open resource
