The CTD data were collected using a CTD-rosette system and includes binned profiles and bottle files along with the header files. The physical and chemical properties in the water column at the ECOGIG seep and other study sites were characterized. The water column and sediment chemistry data includes water column salinity, pH, concentration of dissolved nutrients, dissolved gases, total particulate nitrogen (TPN), total particulate carbon (TPC), particulate organic carbon (POC), and particulate inorganic carbon data acquired from 40 CTD casts and 11 multiple corer drops. The purpose of this cruise was to assess the impacts of the Deepwater Horizon blowout on sediment and water chemistry on fallout sites and compare these impacts to naturally occurring oil and gas seeps.

NOAA National Centers for Environmental Information custodian CTD CTD Conductivity-Temperature-Depth probe fluorometer fluorometer fluorometer Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) MOCNESS is a much-improved, high-tech version of the humble sampling net. The letters in MOCNESS refer to the specific improvements: it's a Multiple Opening and Closing Net, with an Environmental Sensing System. As MOCNESS tows behind a research ship, each net can be opened and shut independently so that it samples a discrete patch of water. The researcher chooses exactly when by using the environmental sensing system. This is an array of sensors mounted on the instrument frame that relays water conditions up to the ship in real time. The data also help researchers match what they find in their sample to the physical properties of the seawater. PAR Sensor PAR Sensor Photosynthetically Active Radiation Sensor The PAR sensor measures global solar radiation from 400 to 700 nm, which approximates the spectral band active in photosynthesis. The response of the instrument falls sharply to zero on either side of this band, and between 400 and 670 nm it increases monotonically from about 50% to 100%. There is no protective glass dome over the receiving surface. Irradiance from the sun passes through a small white visible bandpass filter/diffuser in the shape of a horizontal disk at the top of the instrument. Within the instrument radiation is directed through a series of colored glass filters and onto a silicon photodiode detector. The factory-supplied calibration converts the signal from the detector to a flux of photons in micro-mole (of photons) s-1 m-2. (One micro-mole equals 6.022 E17 photons.) For the solar spectrum, these units may be converted to watts per square meter by dividing by 4.6.
