| whole table |
This table contains deployment info for acoustic receivers affiliated with Block Lab acoustic detection data. A deployment represents a specific period of time at a specific location and is denoted by the fields receiver and receiver_dnum. The geographic name for the deployment is broken down into three levels by area of influence - station, site and region. These levels are subjective. Joins to acoustic_data with receiver and receiver_dnum. |
| atn_site |
Not yet implemented but could make identifying site on ATN easy. Where 1 is true. |
| bottom_depth_m |
Bathymetric depth at receiver location. |
| cable_len |
Length of hydrophone cable used with a VR4G or VR2C receiver. |
| comments |
General comments not easily fitting in other fields. |
| deploystamp |
The date with or without time at deployment. Local time. |
| dlatdd |
Decimal degree latitude position of deployment. |
| dlondd |
Decimal degree longitude position of deployment. |
| downloadid |
A unique date time generated ID associated with a specific file ingestion. |
| hydrophone |
The hydrophone serial number used with a VR4G or VR2C receiver. |
| lost_missing |
If the receiver was lost or is currently missing then will have a value of 1. |
| permit |
Is the deployment permitted? Or what permit is it on? |
| project |
The agency or group affiliated with the deployed, e.g., TOPP, OTN or Hydra. |
| receiver |
Unique ID of deployed receiver. Each receiver can be deployed multiple times. |
| receiver_depth |
Depth of receiver below surface in meters. |
| receiver_dnum |
This value reflects a specific deployment event for an individual receiver. Used along with receiver field to join with acoustic_data table. |
| region |
The largest geographic location area of deployment, e.g., Chagos, Mid-Atlantic Bight or Gulf of St Lawrence. |
| riser_m |
Not sure but possibly distance off bottom in meters |
| site |
The mid size geographic area of deployment, e.g., Farallones, Ano Nuevo or Tomales. |
| station |
The most specific geographic location area of deployment, e.g., West Farallones, Ano North or PB19. |
| substrate |
Substrate of seafloor at deploy site. |
| type |
The receiver type, e.g., VR2W, VR2C or VR4G. |
