Abstract:

This dataset contains meteorological and oceanographic data collected by the Central Gulf Ocean Observing System (CenGOOS) buoy in the Gulf of Mexico from 2017-01-01 to 2017-07-26. This buoy was moored south of Horn Island in 20 m of water at 30.0424 ˚N and 88.6473˚W. The buoy collected both meteorological and oceanographic data including air temperature, relative humidity, wind speed and direction, barometric pressure, current speed and direction, current profiles, and significant wave height and period. Other related datasets from the year 2015 and 2016 are available under GRIIDC Unique Dataset Identifiers (UDIS) R4.x260.204:0003 (DOI: 10.7266/n7-eep5-5k62) and R4.x260.204:0013 (DOI: 10.7266/n7-ejqc-vk96) respectively. All datasets are archived by the University of Southern Mississippi (USM). The meteorological and near-sea surface temperature, salinity, and waves data are also archived through the National Data Buoy Center (NDBC; identified as Station 42067).

Purpose:

To collect meteorological and oceanographic data.

Data Parameters and Units:

Date and Time [Date (MM/DD/YYYY) and time (HH:MM) of the measurement in UTC]; latitude [degrees N]; longitude [degrees W], airtemp [air temperature (°C) at the instrument]; pressure [Barometric pressure (in mBars)]; humidity [Relative humidity]; compass_heading [Compass heading of the instrument (degrees)]; compass_magnitude; wind_heading [Raw heading (degrees)]; wind_magnitude [Speed of the wind (m/s)]; gust_heading [Raw heading (degrees)]; gust_magnitude [Speed of the gusts (m/s)]; corrected_wind_heading [Heading (Degrees true)]; corrected_gust_heading [Heading (Degrees true)]; rawstart [Start time of the measurement in UTC]; rawend [Ending time of the measurement in UTC]; sig_height [Significant wave height (m)]; mean_period [Average wave period (s)]; dom_period [Dominant wave period (s)]. Note: All-time units are UTC and the measurements were taken from an instrument mounted on a 3m discus buoy moored at 30°02.5295'N, 88°38.8457'W.

Methods:

Air temperature data: The instrument (Gill Metpak) was mounted on a mast on the buoy ~5m above the sea surface. Barometric pressure data: The instrument (Gill Metpak) was mounted on a mast on the buoy ~3m above the sea surface. Relative humidity data: The instrument (Gill Metpak) was mounted on a mast on the buoy ~5m above the sea surface. Wind speed data: The instrument (RM Young anemometer) was mounted on a mast on the buoy ~5m above the sea surface. Wave statistics data: The instrument was (Crossbow DMU) was mounted centrally in the buoy.
