ESD_DS_DataDict_2015_CT_H2O

Unique identifier for each Diel Suite deployed

Defined as the Ship ICES code + departure date formatted as YYYYMMDD

Mission Identifier

More descriptive name of cruise/mission and is usually in the format [MissionID]-[REGIONDesignation]-[IslandCode if only one visited]

A single designation that applies to all the rounds associated with a given mission/cruise

A 3-dimensional identifier for the fixed location (LATITUDE and LONGITUDE) and depth where the subsurface temperature logger (STR) was deployed at the island or atoll (LOCATION). Includes "OCC" prefix, a 3-letter location code (derived from LOCATION), and a 3-digit site number. A newly deployed instrument is assigned to a pre-existing OCC_SITEID if its coordinates are within a 100-m diameter and its depth is within a 3-m depth cylinder of a pre-existing OCC_SITEID, otherwise, the instrument is assigned a new OCC_SITEID.

An identifier for the ecological site at the island or atoll (LOCATION) associated with the diel survey. Combines a 3-letter island code (derived from LOCATIONCODE) with a 2-4 digit site number.

The name of the region where the diel survey was conducted in the Pacific Islands region: American Samoa, Pacific Remote Island Areas, Mariana Archipelago, main Hawaiian Islands, Northwestern Hawaiian Islands.

Name of island or atoll where the sample was collected in the Pacific Islands region (REGION).

3-Letter unique code for LOCATION.

Code for the region surveyed in the Pacific Islands region: American Samoa (SAMOA), Pacific Remote Island Areas (PRIA), Mariana Archipelago (MARIAN), main Hawaiian Islands (MHI), Northwestern Hawaiian Islands (NWHI).

Latitude in decimal degrees, WGS84, for the given Site

Longitude in decimal degrees, WGS84, for the given Site

Unique numeric ID of CTD cast (4-digit number).

Unique numeric identifer for each water sample (4-digit number) associated with Station_ID and Cast_number

An identifier for the station at the island or atoll (LOCATION) associated with the sample. Combines a 3-letter island code (derived from LOCATIONCODE) with a 2-4 digit site number.

Indicates if water sample is discrete (Single) or if the sample is part a series of water samples collected ~every 4 hrs in a ~24-hr period at the same STATION_ID using a Programmable Underwater Collector (Diel).

Depth at which sample was collected (meters).

NCRMP survey design associated with the sample. Survey designs include: samples collected by small boat at permanent climate sites (Permanent); samples collected by small boat and co-located with fish or benthic stratified random survey sites (Stratified_Random); samples collected by small boat at random sites not associated with climate, benthic, or fish sites (Random); shipboard samples collected offshorefor end member data (End_member); and shipboard samples collected to calibrate underway systems (Calibration).

4-digit year of the water sample collected by a Programmable Underwater Collector (PUC)

Numeric day in UTC of water sample collected by a Programmable Underwater Collector (PUC)

Numeric month in UTC of water sample collected by a Programmable Underwater Collector (PUC)

Date and time of water sample in UTC

UTC time of water sample collected by a Programmable Underwater Collector (PUC), hh:mm:ss in 4-hr intervals.

Decimal value of the days, hours, and minutes from the beginning of the year

Water sampling interval in seconds, as programmed by PUC

Calculated aragonite saturation based on CTD measurements made during sample collection. Calculated from DIC, TA, temperature, salinity and pressure.

Dissolved inorganic carbon measured in micromoles per kilogram. NULL values result from insufficiently filled sample bags in which the sample volume only allowed for TA analysis.

Flag for dissolved inorganic carbon values

Partial pressure of carbon dioxide, calculated from DIC, TA, temperature, salinity, and pressure.

pH calculated on Total Scale (TS) from DIC and TALK

Pressure calculated from depth (using the R package "oce") for samples not associated with a CTD cast

Hydrostatic pressure recorded from CTD at the depth where the sample is taken

Best salinity value associated with the sample, derived from either SALINITY_PSS78_CTD, SALINITY_PSS78_BOTTLE, or SALINITY_PSS78_SCS.

source of 'SALINITY_PSS78_BEST' measurement: CTD (SALINITY_PSS78_CTD), discrete bottle sample (SALINITY_PSS78_BOTTLE), or SCS (SALINITY_PSS78_SCS)

Salinity calculated from conductivity measured from discrete bottles using the equation of the Practical Salinity Scale of 1978

Quality control flag for TALK; TA_QC from V_OCC_A_H2O_FIELDDATA_OBS

source of 'TEMPERATURE_ITS90_BEST' measurement: CTD (TEMPERATURE_ITS90_CTD) or SCS (TEMPERATURE_ITS90_SCS)

Best temperature value associated with the sample, derived from either TEMPERATURE_ITS90_CTD or TEMPERATURE_ITS90_SCS

In situ temperature recorded from CTD with the scale of ITS-90.

Quality control flag for CTDTEMP
