The survey was designed to detect natural oil seepage over a large region of the Perth Basin, Western Australia, in an effort to refine the petroleum prospectivity assessment.\nAn area of about 80km by 400km was surveyed at 5km line spacing. A total of 510,500 fluorosensor spectra were recorded.\nThis report is a re-interpretation of the BP data by Signalworks Pty Ltd using the ALF Explorer software. A total of 1,355 fluors were picked out of the 510,500 recorded spectra in the final interpretation. This is an average fluor density of 2.65 fluors per thousand spectra.\nThe fluorescence response over most of the survey area consisted mainly of relatively low confidence fluors (compared to the more reliable MkIII survey data). High intensity fluors are located in several zones in the middle of the survey, probably over small islands, being caused by the exposed island material fluorescing.\nWhile fluor density variations can be seen on the fluor map the geological implications are not clear. Because of its susceptibility to noise, the MkII ALF system produces less confident fluor maps than the MkIII system. Some mapped fluor density variations may be influenced by sea state or water property variations", "num_resources": 3, "num_tags": 6, "organization": {"id": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "name": "geoscience-australia-data", "title": "Geoscience Australia Data", "type": "organization", "description": "Harvester for Geoscience Australia Data", "image_url": "", "created": "2025-06-23T12:29:08.024111", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://ecat.ga.gov.au", "href": "https://ecat.ga.gov.au/geonetwork/srv/eng/csw/dataset/mk-ii-airborne-laser-fluorosensor-survey-reprocessing-and-interpretation-report-perth-basin-wes", "title": "Geoscience Australia"}, "owner_org": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "private": false, "promotion_level": "0", "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[112.0, -31.0], [115.0, -31.0], [115.0, -26.0], [112.0, -26.0], [112.0, -31.0]]]}", "spatial_coverage": "{\"type\": \"Polygon\", \"coordinates\": [[[112.0, -31.0], [115.0, -31.0], [115.0, -26.0], [112.0, -26.0], [112.0, -31.0]]]}", "state": "active", "temporal_coverage_from": "2018-04-20 06:04:19", "title": "Mk II Airborne Laser Fluorosensor Survey Reprocessing and Interpretation Report: Perth Basin, Western Australia", "type": "dataset", "unpublished": false, "url": null, "version": null, "extras": [{"key": "harvest_object_id", "value": "1381737f-ffcf-4e7c-a38d-a0701de0d63f"}, {"key": "harvest_source_id", "value": "00080910-39e7-408f-882c-e6e1eb6baadb"}, {"key": "harvest_source_title", "value": "Geoscience Australia"}], "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2025-10-16T16:32:16.673847", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "Download the Record (pdf)", "format": "PDF", "hash": "", "id": "58851813-470f-4272-a6d8-3494eb8c6f1d", "last_modified": null, "metadata_modified": "2025-10-16T16:32:16.664378", "mimetype": null, "mimetype_inner": null, "name": "Download the Record (pdf)", "package_id": "98ebf5f1-cd21-4d61-8963-5b87937a8107", "position": 0, "resource_locator_function": "information", "resource_locator_protocol": "WWW:LINK-1.0-http--link", "resource_type": null, "size": null, "state": "active", "url": "https://d28rz98at9flks.cloudfront.net/35927/Rec2001_019.pdf", "url_type": null, "zip_extract": false}, {"cache_last_updated": null, "cache_url": null, "created": "2025-10-16T16:32:16.673852", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "Download the file (misc)", "format": "ZIP", "hash": "", "id": "6e5f4d9d-d19c-400f-a404-c0d2422ae34d", "last_modified": null, "metadata_modified": "2025-10-16T16:32:16.664511", "mimetype": null, "mimetype_inner": null, "name": "Download the file (misc)", "package_id": "98ebf5f1-cd21-4d61-8963-5b87937a8107", "position": 1, "resource_locator_function": "information", "resource_locator_protocol": "WWW:LINK-1.0-http--link", "resource_type": null, "size": null, "state": "active", "url": "https://d28rz98at9flks.cloudfront.net/35927/data.zip", "url_type": null, "zip_extract": false}, {"cache_last_updated": null, "cache_url": null, "created": "2025-10-16T16:32:16.673853", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "", "format": "HTML", "hash": "", "id": "049a3a79-3044-46fa-97a6-2b22a56a27ab", "last_modified": null, "metadata_modified": "2025-10-16T16:32:16.664614", "mimetype": null, "mimetype_inner": null, "name": "Unnamed resource", "package_id": "98ebf5f1-cd21-4d61-8963-5b87937a8107", "position": 2, "resource_locator_function": "", "resource_locator_protocol": "", "resource_type": null, "size": null, "state": "active", "url": "http://www.abs.gov.au/ausstats/abs@.nsf/Latestproducts/1297.0Main%20Features32008?opendocument&tabname=Summary&prodno=1297.0&issue=2008&num=&view=", "url_type": null, "zip_extract": false}], "tags": [{"display_name": "AU-WA", "id": "7df0c8ad-c403-4153-83c3-ec287b0e6ee7", "name": "AU-WA", "state": "active", "vocabulary_id": null}, {"display_name": "Earth Sciences", "id": "40d58e59-cdeb-4021-9e5a-aae60edebdf5", "name": "Earth Sciences", "state": "active", "vocabulary_id": null}, {"display_name": "GA Publication", "id": "e62fc1f2-3d55-4d1e-bd88-116cd26bc3fd", "name": "GA Publication", "state": "active", "vocabulary_id": null}, {"display_name": "Published_External", "id": "5178775c-8044-4b7f-881f-5428a4e2d925", "name": "Published_External", "state": "active", "vocabulary_id": null}, {"display_name": "Record", "id": "c66268f2-6d34-481b-8962-fd48c58ae831", "name": "Record", "state": "active", "vocabulary_id": null}, {"display_name": "remote sensing", "id": "56a85ee9-f3ed-4b35-8d39-f15208521605", "name": "remote sensing", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": []}}
