cft_rcvrs {filteRjsats}

Example receiver data from CalFishTrack

Description

A dataframe of acoustic receiver metadata downloaded from ERDDAP representing receivers deployed from 2021-2022.

Usage

cft_rcvrs

Format

cft_rcvrs

A dataframe of 1,130 rows and 12 columns:

dep_id

a unique number that identifies a single deployment

receiver_serial_number

the serial number of the acoustic receiver that recorded the detection. If this value is 1, then the record is not a receiver detection but is the release date-time and location. Every tagged fish has at least one record in the table

receiver_general_location

A name for the geographic location of one or more receivers.

receiver_region

A name for a larger geographic region that defines a subarea of the Central Valley watershed. Some regions are Upper Sac R, Lower Sac R, Feather R, East Delta, West Delta, SF Bay.

receiver_location

The name for the location of a single receiver

latitude

Latitude for the exact location of a single receiver. If unknown = cell is blank

longitude

Longitude for the exact location of a single receiver. If unknown = cell is blank

receiver_river_km

River kilometer for the location of a single receiver. Must be unique for each GPSname. The Golden Gate Bridge is rkm 0. Values increase the further upstream

receiver_make

Describes the manufacturer and type of JSATS receiver.

receiver_depth

the estimated depth of the receiver hydrophone. If unknown = blank

receiver_start

The date and time in Pacific Standard Time when the receiver was deployed (put at the site in the water). Format: date time M/DD/YYYY HH:MM

receiver_end

The date and time in Pacific Standard Time when the receiver was recovered (removed from the water). Format: date time M/DD/YYYY HH:MM

receiver_last_valid

Taken from the detection data file for this deployment, the date and time in Pacific Standard Time of the last valid detection or sensor data entry. This time cannot be greater than the EndTime, but can be less that the EndTime if receiver quit recording data or was pulled out of the water. Format: date time M/DD/YYYY HH:MM

receiver_data_coverage

describes how extensive the data is for this receiver deployment. If the receiver failed to work or was lost and not recovered = none. If it worked for part of the deployment = partial. If the receiver worked the entire deployment = full. Can be blank.

receiver_coverage_problem

If the receiver did not work until EndTime then an entry here describes the reason why the receiver may have failed.

receiver_agency

The agency (abbreviated) managing the receiver deployment.

receiver_beacon_id_hex

The hex code of the beacon tag associated with this receiver deployment

receiver_beacon_id_dec

The decimal code of the beacon tag associated with this receiver deployment

receiver_beacon_pri

The pulse rate interval of the beacon tag in secs, usually 60 or 30 secs
