This data type contains data from chemical analysis of seawater samples. Cruise information, position, date and time is reported for each station along with sample depth, temperature, salinity and density (sigma-t). Chemical and biochemical parameters that may be reported include: dissolved oxygen, nitrate, nitrite, ammonia, inorganic phosphate and silicate; dissolved organic carbon, particulate organic carbon and particulate organic nitrogen; and apparent oxygen utilization, percent oxygen saturation, adenosine triphosphate, total phaeophytin, total chlorophyll, total suspended matter, total recoverable petroleum hydrocarbons and total resolved light hydrocarbons.

Data has been processed by NODC to the NODC standard Wave/Current Observations (F181) format. The F181 format is designed to support studies made by automated ocean sensoring devices. The format consists of ten record types. Record types A and B describe the basic environmental information to understand the data. Record types C, D, E, F, G, H, I, and J are used to report current meter, water level, pressure gauge, wave height, and wave direction, spectra, fourier coefficients, and current meter respectively.

This data set contains time series measurements of seawater pressure from anchored or bottom-mounted sensors. Measurements of variations at depth of seawater pressure provide information on tidal and storm flows, ocean circulation and other phenomena that cause changes in sea surface elevation or slope and that can be detected from their pressure signature. Position, bottom depth and gauge depth are reported for each station. The data record comprises values of total pressure at specified date and time. Data values may be subject to averaging or filtering and are typically reported at time intervals of 10 - 15 minutes. Seawater temperature may also be reported. Comments may be reported in a text record.

NODC Accession 0098794 contains physical and chemical oceanographic profile data collected aboard multiple ships worldwide from 1959-05-26 to 2012-06-03. These data include AIR TEMPERATURE - DRY BULB, AIR TEMPERATURE - WET BULB, BAROMETRIC PRESSURE, BIOLOGICAL DATA, CHLOROPHYLL, DEPTH - BOTTOM, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRITE, PARTICULATE ORGANIC CARBON, PHAEOPHYTIN, PRIMARY PRODUCTIVITY, SALINITY, SEA STATE, Secchi dEPTH, TOTAL ALKALINITY (TA), WATER TEMPERATURE, WAVE HEIGHT, WAVE PERIOD, WEATHER, WIND DIRECTION, WIND FORCE, WIND SPEED, cloud amount/frequency, cloud types, nitrate + nitrite content (concentration), pH, phosphate, and silicate. The instruments used to collect these data include CTD, bathythermograph - XBT, bottle, meteorological sensors, and Secchi disks. Mathieu Ouellet from Fisheries and Oceans Canada submitted these data, which were collected by multiple organizations.

The World Ocean Atlas 2005 (WOA05) contains data files of objectively analyzed climatologies and related statistical fields of temperature, salinity, dissolved oxygen, Apparent Oxygen Utilization (AOU), percent oxygen saturation, phosphate, nitrate, and silicate for the world ocean. The data are available in two different ASCII formats (native gridded format and comma separated value format) on the DVD. The data used to generate these statistics are available on DVD as the World Ocean Database 2005 (WOD05). World Ocean Atlas 2005 Figures (WOA05F) (3 discs) contains a collection of "JPEG" and high resolution "PDF" images of objectively analyzed fields and statistics generated from the World Ocean Atlas 2005. The ocean variables included in the atlas are: Disc 1: Temperature and Salinity Disc 2: Oxygen (dissolved oxygen, apparent oxygen utilization, and percent oxygen saturation) Disc 3: Dissolved inorganic nutrients (phosphate, nitrate, and silicate)
