Invertebrate census data were collected from sites around Micronesia as part of the ongoing Micronesia Challenge. Information on the program can be found at (www.micronesiareefmonitoring.com). Survey sites were selected around each island to be representative of natural environmental gradients, management, and major reef types. Thus, full site designs can be used to evaluate both island trends and site-specific trends. Benthic substrates were evaluated using a photo-quadrat technique. At each site, five 50-m transects were used to measure fishes, corals, and other benthic assemblages between 8–10 m on outer reefs, and at 3–5 m for inner lagoon reefs. Each 50-m transect was surveyed at a 5-m width by either one or two observers. Invertebrates were identified to the lowest possible taxon and enumerated. When possible, a size esitmate to the nearest 5 cm was provided.
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 330 records.
2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
The table below shows only published versions of the resource that are publicly accessible.
