The CTD data were collected using a CTD-rosette system. The physical and chemical properties in the water column at the Ecosystem Impacts of Oil and Gas Inputs to the Gulf (ECOGIG) seep and other study sites were characterized. The ship departed Gulfport Mississippi on cruise EN515 on 2012-09-05 to collect samples at ECOGIG and other sites before returning to Gulfport on 2012-09-16. The dataset includes binned profiles and bottle files along with the header files. 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 19 CTD casts and 5 multiple corer drops. The elemental and isotopic data includes the delta 13C and 15N, total Nitrogen and Carbon, and the C/N ratio. The particle samples were collected using a CTD-rosette and a MOCNESS. Time series photographs were obtained from a marine snow profiling camera on short-term moorings. Vertical profiles of size-specific particle abundance were taken from Snowcam/Fluxcam moorings near lease blocks GC600 (profiles 1-2) and OC26 (profiles 3-5) in the Green Canyon and Mississippi Canyon, respectively. The camera, a Nikon Coolpix 995, was lowered at a steady rate of 10m/min to just above the seafloor. Images were captured every 11 seconds. The objectives were to characterize the physical and chemical properties in the water column at/near cold seeps in the northern Gulf of Mexico. All the data records also include sampling information (time, date, location, collection type, and depth). This dataset is available to the public for a wide variety of uses including scientific research and analysis.

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.
