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: | Echosounder data from goliath grouper aggregations in Jupiter, FL from August 31 until November 30, 2020 (NCEI Accession 0291747) |
| Abstract: | This dataset contains data collected in the North Atlantic Ocean from 2020-08-30 to 2020-11-29. These data include depth. The instruments used to collect these data include Simrad EK80 echo sounder and Split-Beam Echosounder. These data were collected by Yannis Papastamatiou of Florida International University as part of the "Collaborative Research: RAPID: Storm and tropical cyclone effects on the spawning activity, larval dispersal, and ecosystem impacts of an endangered marine predator (Storm effect on predator)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-01-27. The following is the text of the dataset description provided by BCO-DMO: Hydroacoustics - Jupiter from August 31 until November 30, 2020 Dataset Description: Data have been published “as is”. Final review by the data submitter was not received after it was imported into the BCO-DMO data system. |

| Supplementary information: | Acquisition Description: Hydroacoustic surveys were conducted at three well known artificial reefs in Jupiter, Florida (approximately: 27N, 80W). Sites include MG111 Barge and Warriors Reef (referred to as “mg” in data files), Sun Mariner Tugboat (referred to as “sun” in data files), and the Wreck Train complex (Zion, Miss Jenny, and Esso Bonaire) (referred to as “wrt” in data files). Surveys consisted of 20 350m long evenly spaced (10m) parallel transects. Two Simrad split-beam echosounders (ES38-10 and ES 120-7C) were towed at approximately 2.5m s -1 on a custom built towfish, approximately 12m behind the research vessel (7m center console). GPS position is referenced at the center of the research vessel, but the correction has not been applied to these data. The distance between echosounders and antenna is approximately 15.5m. Data were collected in Continuous Wave (pulse duration: 0.256µs, sampling interval: 10Hz) and Frequency Modulation (pulse duration: 2.048µs, sampling interval: 10Hz) modes at 38kHz (FM: 35-45kHz) and 120kHz (FM: 90-170kHZ) between 31 August and November 29, 2020. Data from 31 August to 15 October were collected in CW, and data from 30 October to 29 November were collected in FM. Echosounders were calibrated using standard techniques described by Demer et al. (2015). Surveys were conducted biweekly during peak new and full moon periods. Missing surveys are attributed to power supply malfunctions and periods of inclement weather. |
