The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Fish count data from the Caroline Islands and the Federal States of Micronesia collected from 2012-2014 (NCEI Accession 0278036) |
| Abstract: | This dataset contains biological and survey - biological data collected at shoreside Micronesia during deployment Bernardi_2012 from 2012-07-03 to 2015-07-08. These data include species. The instruments used to collect these data include Camera. These data were collected by Nicole Crane of Cabrillo College and Giacomo Bernardi of University of California-Santa Cruz as part of the "The impact of a large episodic disturbance on an invasive (outbreak) coral: Will Typhoon Maysak promote or suppress an invasive Montipora sp. Coral on reefs of Ulithi Atoll, Federated States of Micronesia? (DisturbImpactsCoral)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-04-04. The following is the text of the dataset description provided by BCO-DMO: Percent coverage of coral, algae, and inverts. Dataset Description: Fish count data for 2012, 2013 and 2014. Data associated with publication: Crane NL, Nelson P, Abelson A, Precoda K, Rulmal J Jr, et al. (2017) PLOS ONE. |

| Supplementary information: | Acquisition Description: Surveys were conducted using snorkel on the reef crest and the reef table, in shallow sites at depths between 1.5 and 3 meters. Fish community characterization All fish were identified to the species level and counted along 50 m transects, in the same habitat and area as the quadrats, parallel to the reef crest and in 1.5-5 m in depth. The transect count area extended from the sea floor to the surface of the water column and consisted of at least two 50 m long swaths surveyed sequentially at each site. For all transects in all years, the same diver Hirst counted mobile fish on a 5 m wide swath, before returning along the same transect and counting cryptic benthic fishes on a 1 m wide swath. The total lengths of all fishes were estimated to the nearest cm. For analysis of fish community structure, fish species were classified into one of Hive trophic guilds: 1. herbivores, 2. planktivores, 3. corallivores, 4. carnivores, and 5. piscivores. Species that have a wider trophic range (omnivores) were categorized by their main food preference according to the 5 categories mentioned above. Biomass was estimated using the published length/weight relationships most appropriate for the region (Adam et al., 2011; Froese & Pauly, 2000; Kulbicki et al., 2005). Sharks and large rays were occasionally seen on transects, but their overall low abundance makes band transects a poor approach to estimate their actual numbers and contribution to biomass. Therefore elasmobranchs were recorded, but not included in our calculations here. |
