Reef Support Marine Data
Underwater imagery with masks, boxes, points and image labels for coral-reef computer vision, harmonised into one label space, with the licence and attribution of every row recorded.
Open flavour: every source here allows commercial use (per-source licences and attribution below).
Dataset summary
Reef Support Marine Data v1.1.0 adds 11 configurations to the frozen v1.0 release, additively: image bytes once per image_sha256, per-image metadata, point, box, mask and bleaching labels, benthic cover and sites, and the tables that describe the label space (taxonomy, label-map) and the sources. Every row carries its image_sha256, so any label reaches its pixels in one join, and licence and attribution stay attached to the pixels.

Keys: the image key is image_sha256 (64 lowercase hex, the staged checksum, never recomputed from re-encoded bytes); metadata.bytes_sha256 is the hash of the embedded bytes. The annotation key is image_sha256 + source_id + source_version + ann_id. metadata.bytes_config names the config that holds each image's pixels: a v1.0 config or images. The Hub splits are train, validation, test and test_ood.
Masks. A semseg row names a v1.0 mask config in mask_config when that frozen config holds the image's mask, and the mask stays there; otherwise the mask is embedded in the row as a palette PNG. The instances table carries no masks: each row holds the instance's polygon or rle (or a mask_ref pointer), instance_id, the native label with its taxonomy nodes and match_type, annotator_type and ann_license, and the instance masks stay in the v1.0 instance-masks config.
Label space
Labels are harmonised into the pinned taxonomy release (taxonomy_version is stamped on every row of every new table). Three axes per row: taxon_node_id, form_node_id and condition_node_id, with nodes keyed <schema>:<id>. rs-benthic-v1 is the functional schema (L0 biotic/abiotic, L1 phyla, L2 the 14 MariMap codes, L3 genera), rs-taxa-v1 the identity schema (A<AphiaID> nodes, AphiaID also shipped as worms_aphia_id) and rs-fauna-v1 the fish and fauna schema. Node ids are namespaced in taxonomy 3.0.0: an rs-taxa-v1 id is A followed by the WoRMS AphiaID, and the non-taxon nodes of rs-benthic-v1 and rs-fauna-v1 (debris, equipment, divers, wrecks, seafloor, unknown) carry NT_* ids. label-map maps each source's raw labels to these nodes, one row per source and native label or pixel value. match_type is exact, broader, narrower, related or unmapped; narrower is stored for audit and never used as a positive. A native label with no mapping is a row with match_type = unmapped and null node columns, never dropped, so the unmapped labels of each source are listed in label-map (the mapped share per source is tabulated below); the training views send them to 255 (ignore).

Splits
The card publishes the measured split shares of every config, never a nominal ratio: upstream splits dominate several sources, so the v1.0 shares are not 80/10/10 or 70/15/15. New rows target 70/15/15 with the split names train, validation, test and test_ood. Precedence, first match wins: (1) an image that matches a v1.0 image by sha256, or within Hamming distance 4 of its dhash, keeps that v1.0 split unless an upstream benchmark manifest pins it (see below), and an image within 5-8 of a v1.0 image is never used across the train/eval boundary; (2) the out-of-distribution holdout rules (deepfish, temperate-australasia, mediterranean, a data-driven tropical province, depth of 800 m or more, platform AUV, year 2025 or later) go to test_ood, which is never mixed into test; (3) the upstream split where defined; (4) a group hash on survey, site or quadrat, else the near-duplicate group. Images of one group share a split. Group keys in SPLIT_MAP.json are namespaced <source>/<id>, so equal ids in two sources are two groups.
Version 1.1.0 inherits the v1.0 splits by image_sha256 from the published v1.0 tree, with one exception: six benchmark sources (coralscapes, suim, uiis, uiis10k, usis10k and one benchmark not distributed in the open release) are pinned to their upstream manifests. A pin routes the manifest's evaluation split to test and a second held-out split, where the source has one, to validation. A pin wins over an inherited v1.0 split; the out-of-distribution holdout and any rule that keeps an image out of evaluation win over a pin. The pins moved images that were in v1.0 train into the v1.1.0 validation and test splits and resolved near-duplicate groups that straddle v1.0 splits, while the frozen v1.0 configs keep their v1.0 splits. A group that cannot be assigned consistently is withheld from every table and listed under withheld in SPLIT_MAP.json.
Because several of these sources carry large upstream test sets, the overall split is not the 70/15/15 target: the test share is well above 15 %, and boxes and instances are the most affected tables.
Evaluation caveat. A model trained on the v1.0 configs must not be evaluated on the v1.1.0 validation or test splits of these six sources, because some of their images were in train in v1.0.
Left out and overridden (v1.1.0). No group was withheld. The split map also leaves out 215 images that sit in the prior-release near-duplicate band (dHash distance 5 to 8) of v1.0 train and evaluation images, on the side their near-duplicate group did not keep, and 51 images that each collide on the DCT pHash-64 with an image of another split (one image of the pair goes, never a v1.0 image); these 266 images ship in no split of any config. Where a benchmark pin and v1.0 continuity disagree the pin wins, and it resolves the near-duplicate groups that straddle v1.0 splits: the pins overrode the v1.0 split of 4,544 images (pins.v1_continuity_overridden in SPLIT_MAP.json).
Ratios. The 70/15/15 target is checked per source family, over distinct images, not per config. The NOAA bleaching images, the Roboflow Coral Universe forks and the Seaview sources measure 70.8 / 14.6 / 14.6 %, 68.5 / 15.7 / 15.8 % and 67.6 / 12.6 / 19.8 % (train / validation / test); pinned benchmark sources and strata under 100 images (roboflow-aquarium) are left out of the check. Row shares of a config therefore deviate, as the table shows: points rows are 65.2 / 12.7 / 22.1 % (its 11,356 distinct images 67.1 / 12.8 / 20.2 %) and semseg rows 74.1 / 8.9 / 16.9 %. noaa-pifsc-bleaching is assigned by whole site: its 236 sites went 42 to train, 97 to validation and 97 to test, so its image shares are not its site shares.

Build and gates
Built with the marine-data registry; every source is admitted only after its licence is recorded, and the licence gate raises, never warns. The release is pinned by provenance/release.lock.yaml. Gate results are published as provenance/GATES.json. Near-duplicate images inside one split that come from different Roboflow Universe forks of one image set, or from the Seaview survey imagery and our labelled copies of its photographs, are disclosed, not removed: the dedup gate counts them as near_pairs_across_sources_in_family in provenance/GATES.json, and a near-duplicate across splits still fails it. In v1.1.0, 5,201 such pairs are disclosed. A further 6 pairs from different sources fall within the pHash-64 threshold (8 bits) but are kept: the pHash-256 of the two images differs by more than 32 bits and both carry at least 4 bits of grey entropy, so the gate waives them as look-alikes and counts them as near_pairs_across_sources_unconfirmed.
Personal and sensitive information
The images are underwater and reef photographs. Divers, and rarely faces, can appear. The release gates include a privacy pass (face detections at a score of 0.85 or more are excluded, 0.60 to 0.85 are flagged) and a check for EXIF GPS; their results are published in provenance/GATES.json. Images the detector flags are reviewed on contact sheets: an image with an identifiable person is withheld from every table, and a detection that proves to be a false positive is recorded in registry/privacy/review.yaml in the code repository. No image with an identifiable person is published knowingly; one Roboflow fork was excluded from this release for that reason (see Excluded sources). A gate and a review lower the risk; they do not remove it. The EXIF GPS of seaview-survey-imagery images is retained by design, because that source publishes per-image coordinates. metadata carries position at the precision the source provides (coord_precision_m) and no source is currently flagged location-sensitive in the registry. In v1.1.0 the privacy gate scanned 32,200 images: 10 flagged images were reviewed by hand and cleared, none was withheld and no unreviewed detection remains. Divers are an annotated class, kept on purpose: coralscapes, uiis, uiis10k and usis10k label them (human and human divers, 7 label-map rows). No face or person identification is intended or supported. To drop the class, filter out the rows whose taxon_node_id ends in NT_DIVER (label-map lists the labels that map to it) and send its value to 255 (ignore) in the masks.
Limitations and known defects
- Coralscapes has no soft-coral or octocoral class.
label-maprecords the absent classes, so a model trained on Coralscapes alone cannot predict them and cover for them is undercounted. - Absence is not a negative. For the reef-support and Seaview label sources
255means unannotated, not background; Coralscapes uses its own ignore id.label-mapcarries the per-source ignore semantics. - Cross-source benthic training should use the coarse training views, or mask the classes a source cannot contain: the label overlap table shows how few classes more than one source reaches.
- Labels without a taxonomy mapping are kept (
mapped = false) and ignored in the training views. A source whose mapped share is below the 95 % floor is listed in the sources table with its share. - Until the declared bridges from
rs-taxa-v1tors-benthic-v1andrs-fauna-v1exist, rows labelled by an identity node carry a nullrs_benthic_code. - A small number of identical images carry conflicting labels; every party has
label_status = conflictand all rows are kept. The sampled label-quality audit has not been run. - Confidence is present only where the upstream source supplies it; forks and crowd sources have none. It is never invented.
- v1.0 files are frozen as published, with their known defects: Seaview rows say
CC-BY-3.0-AUwhere the University of Queensland licence is CC BY 3.0 unported (new rows andmetadata.licensesayCC-BY-3.0); v1.0fish-boxesuseslicense,source_idand int32 where the other configs uselicence,sourceand int64; v1.0 masks render black in the viewer because they hold class ids, not colours (new semantic masks carry a palette). - Coordinates, dates and depths are as complete as each source made them; analytics resolvers exist for a subset of the sources.
- The images of
seaview-survey-imageryare inimagesandmetadata, and its point labels are inpointsonly; no Seaview row is part ofbenthic-cover: the cover rollup reads the original point sources, and Seaview points stay out of it until a cover decision is made for that source. - Licensing and provenance caveats. Four sources are forks of Roboflow Universe projects (
roboflow-coral-bleaching-final-v6i,roboflow-coral-bleaching-general-v1-yolov8s,roboflow-coral-classification-copy-changed-v13i,roboflow-coral-reef-classification-v3i). They are web-scraped photo sets re-shared on Roboflow. Their CC-BY-4.0 tag is the uploader's claim, which Reef Support could not verify with the original photographers, and third-party watermarks appear sporadically. Near-duplicate images across these four sources are reported by the dedup gate and are not removed. A fifth Roboflow fork is excluded from this release: its images are augmented broadcast-video frames that show identifiable people, and its licence cannot be verified. Rights holders can use the takedown route below. - 24 hidden-test images that v1.0 does not already publish are withheld from this release: they appear in none of its configs. The 1,226 hidden-test images that v1.0 already published are not withheld: they stay in v1.0 and in the new tables.
- Sources below the 95 % mapped floor:
noaa-pifsc-bleaching(0.0 %),roboflow-coral-bleaching-final-v6i(0.0 %),roboflow-coral-bleaching-general-v1-yolov8s(0.0 %),roboflow-coral-classification-copy-changed-v13i(0.0 %),roboflow-coral-reef-classification-v3i(0.0 %).
Licensing
The data are not under one licence. Every row records its licence, annotation_licence and attribution; the matrix lists each source. Combine sources only in ways each licence allows. LICENSE and NOTICE list the same notices. The table records the licences as Reef Support read them from the primary sources and is not legal advice.

Excluded sources
Every registered source that is not in this release falls under one of the reasons below. The sources that are in it are listed in the sources config.
- restricted-nd: no derivatives: a verbatim-only licence cannot cover cropped, resized or re-labelled releases
- internal-only / unknown: no licence granting redistribution was established for these sources (research-use-only or nothing on record)
- per-row licence: sources whose every item carries its own licence are held out until each row's licence is resolved
- A fifth Roboflow fork: tagged release-excluded. Its images are augmented broadcast-video frames that show identifiable people, and its licence tag comes from the uploader's sidecar and cannot be verified
- A sixth Roboflow fork: dropped as a duplicate of an image set already in this release; none of its images is included
- A fish-market photo source: tagged release-excluded and quarantined: out-of-water market photographs of fish
- sonar sources: side-scan and forward-looking sonar imagery is a different sensing modality from the camera images of this release; none is included
- open-licence sources not yet staged: registered sources with an open licence that were not in the v1.1.0 fetch list (for example
noaa-pifsc-esa-coral-icra,marineevtandsalmon-cage) are deferred to a later release - non-image sources: text-only sources such as
oceaninstructhold no images - One non-commercial source: licensed for non-commercial use only; it ships in the separate non-commercial flavour of the release, not in this repository. No other non-commercial source is part of v1.1.0

Versions and changelog
| Version | Date | Notes |
|---|---|---|
| v1.0 | 2026-10-07 | coral-masks, scene-masks, instance-masks and fish-boxes: 8 sources, 58,803 rows. Frozen: files, rows and paths are unchanged in v1.1.0. |
| v1.1.0 | 2026-10-17 | Additive: 11 new configurations. |
- Added (additive; no v1.0 file, row, path or
configs:entry changed): the configsimages,metadata,points,bleaching,boxes,semseg,instances,benthic-cover,sites,label-mapandsources, andtaxonomyin the open repo;LICENSE,NOTICE,CITATION.cff,croissant.jsonandprovenance/. - Unchanged: every v1.0 config, with its files, rows and paths; the release is additive.
- Task layers: the v2 task layers are new tables on the
image_sha256key:metadata,points,bleaching,boxes,semsegandinstances(benthic-coverandsitesare derived from them). - Changed: this card (text only; the v1.0
configs:entries are carried verbatim).dataset_infois written for the new configs only. - Label space: taxonomy 3.0.0. Every new table row carries
taxonomy_version; the Coralscapes class "unknown hard substrate" is unmapped in the new tables; three wrong AphiaIDs were corrected (205902, 206485, 758259). v1.0class_mapcolumns are untouched. - Splits: a split map that inherits the v1.0 splits by
image_sha256(v1.0 continuity); six benchmark sources are pinned to their upstream manifests instead, which moved some images out of v1.0trainintovalidationandtest; the frozen v1.0 configs keep their v1.0 splits (see Splits). - Excluded: a fifth Roboflow fork, and a sixth dropped as a duplicate (see Excluded sources).
- Licences: new Seaview rows and
metadata.licenseuseCC-BY-3.0(v1.0 rows keepCC-BY-3.0-AU, declared above).
