Observation List
Get a list of Observation objects.
### Available end points:
- `/observations/` - Will list all Results in the database
- `/observations.json` - Will return all Results in json format. This can
also be achieved by using the accept header. `application/json`
- `/observations/<object_id>/` - Returns Results object with that id
### Available Methods:
- `GET`
- `HEAD`
### Available filters:
- `title`
- `uuid`
- `keywords`
- `status`
- `result_field`
- `discoveryKeywords`
- `updateFrequency`
- `nonGeographicFlag`
- `publicationState`
- `permissions`
### How to use filters:
These filters can be used like django query filters using __ for related model relationships.
- `/observations/?uuid=d594d53df2612bbd89c2e0e770b5c1a0`
- `/observations/?status=completed`
- `/observations/?results_field__dataPath__startswith=/neodc/esacci`
- `/observations/?discoveryKeywords__name=ESACCI`
- `/observations/?nonGeographicFlag=True`
Filters can be stacked to build an 'AND' relationship. E.g.
- `/observations/?publicationState__in=published,citable&nonGeographicFlag=True`
- `/observations/?publicationState__in=published,citable&discoveryKeyword__name=NDGO0003`

The individual IW images cover approximately 200 km in azimuth and 250 km in the range direction with a pixel spacing of 10 m.

These datasets were collected to investigate local-scale seafloor morphology and to improve understanding of biodiversity patterns and benthic habitat distribution within the CCZ, by scientists from the National Oceanography Centre, Southampton, UK as part of the NERC-funded Seabed Mining And Resilience To EXperimental impact (SMARTEX). The AUV was used to map in high resolution the 0, 1, 16, 30 and 100 km sites. Bathymetric data were processed using Quality Positioning Services (QPS) Qimera 2.7.6, while backscatter data were subsequently processed using QPS FMGT 7.11.2. Tidal corrections were derived at the Long Mooring 1 site using the TMD toolbox, based on the TPXO global tidal inversion model developed at Oregon State University (OSU), and applied to the dataset. CTD-derived sound velocity profiles (SVPs) were then used to further refine the acoustic corrections. Semi-automatic and manual cleaning procedures were carried out to remove erroneous soundings, particularly along the outer swath edges. The 0–1 km site was surveyed during missions AS5M084 and AS5M085; the latter was spatially adjusted through the identification of common seafloor features. Sites at 16 and 30 km were surveyed during mission AS5M089. The 100 km site was mapped during missions AS5M093, AS5M094, and AS5M096, with AS5M093 used as a spatial reference to align the subsequent surveys based on shared geomorphological features. For each site, bathymetric grids were generated at 1, 2, and 5 m resolution, in WGS84 UTM Zone 11N projection, with interpolation applied where necessary to fill gaps between survey lines. Processed .gsf files were then exported to QPS FMGT to produce backscatter mosaics at 0.20 m resolution. Both backscatter and bathymetry data are supplied in .xyz format. Additionally, bathymetry are supplied in ESRI ASCII Raster format, and backscatter as GeoTIFF files.", "keywords": "", "publicationState": "citable", "dataPublishedTime": "2026-05-06T15:46:06", "doiPublishedTime": "2026-05-06T15:46:06", "updateFrequency": "", "status": "completed", "result_field": { "ob_id": "https://catalogue.ceda.ac.uk/api/v2/observations/45872/?format=api", "dataPath": "/bodc/deposits03/soc260087", "oldDataPath": [], "storageLocation": "internal", "storageStatus": "online", "volume": 38478410627, "numberOfFiles": 47, "fileFormat": ".xyz; .asc; .prj; .tiff; .csv; .xlsx" }, "timePeriod": "https://catalogue.ceda.ac.uk/api/v2/times/13158/?format=api", "geographicExtent": "https://catalogue.ceda.ac.uk/api/v2/bboxes/5144/?format=api", "nonGeographicFlag": false, "phenomena": [], "dataLineage": "The data are archived on the British Oceanographic Data Centre (BODC)'s archive at the Centre for Environmental Data Analysis (CEDA) and assigned a DOI.
