+## Dataset summary
 
-> **Licences differ per source.** Everything in this repo is under an open licence (Apache-2.0, MIT, CC-BY-4.0 or
-> CC-BY-3.0-AU), and each requires attribution. Reproduce the `attribution` column when you share or publish results,
-> and see [Sources and licences](#sources-and-licences). This is a statement of the licences we recorded, not legal advice.
->
-> Data with restricted terms (non-commercial, or no licence stated) is **not** here. It lives in the companion repo
-> [`reefsupport/marine-data-nc`](https://huggingface.co/datasets/reefsupport/marine-data-nc).
+Reef Support Marine Data v1.0 (October 2026) collects eight openly licensed sources into four ready-to-train
+configurations: benthic and scene semantic segmentation, instance segmentation and fish detection. Two of the sources
+contain Reef Support's own annotations, and one of them is Reef Support's own reef-survey imagery. Every row carries its `licence` and `attribution`, so provenance
+stays attached to the pixels. The release is built with the [marine-data](https://github.com/reefsupport/marine-data)
+registry, which records the licence of every source before it is admitted.
 
-## At a glance
+All sources in this release are distributed by their authors under open licences (Apache-2.0, MIT, CC BY 4.0 or
+CC BY 3.0), and each requires attribution. Sources without a licence that permits redistribution are not part of it.
+The licences differ per source, so read [Licensing](#licensing) before you share or publish results. That section records
+the licences as Reef Support read them from the primary sources and is not legal advice.

-## How it was built
-
-1. **Source to bucket.** Each source is fetched, its licence checked against the registry, and staged in an object
-   store under a per-config prefix.
-2. **Bucket to Parquet.** The release builder writes sharded Parquet (images and masks embedded) with per-row licence
-   and attribution, class maps, and splits. Each prefix ends with a `CHECKSUMS.sha256` written last.
+## Dataset creation
+
+### Sources
+
+Eight sources contribute images and annotations; [Licensing](#licensing) lists them with their licences and attribution.
+Coralscapes, the Seaview labels and Reef Support's benthic set cover coral-reef benthos. SUIM provides general
+underwater scenes. UIIS, UIIS10K, USIS10K and the Roboflow Aquarium Dataset provide fish, fauna and other underwater
+objects.
+
+### Annotation process
+
+Annotations are the sources' own except where noted. Reef Support drew the masks for the Seaview images, and
+the benthic set is Reef Support's own imagery and annotation. The Seaview masks are decoded from stitched RGB renders
+with a fixed 5-colour palette (Hard Coral = 1, Soft Coral = 2, `0` = unlabelled). Boxes for the UIIS-family sources
+are derived from the upstream instance annotations. Every `annotator_type` in the mask configurations is `human`.
+
+### Build and verification
+
+1. **Source check.** Each source is fetched and its licence is checked against the registry before it is admitted.
+2. **Conversion.** The release builder writes sharded Parquet with images and masks embedded, per-row licence and
+   attribution, class maps and splits. Each configuration ends with a `CHECKSUMS.sha256`.
 3. **Upload.** Every file is checked (size and sha256 against `CHECKSUMS.sha256`) before and after upload, and row
-   counts are compared with the build. Then the card is written.
+   counts are compared with the build.
 
-Verify a local snapshot: `grep ' data/' docs/<config>/CHECKSUMS.sha256 | sha256sum -c -` (macOS: `shasum -a 256 -c`).
-The code is in the [GitHub repo](https://github.com/reefsupport/marine-data) (`src/marinedata`, release builder in `hf_export.py`).
+Each configuration has release notes in `docs/<config>/`: `README.md`, `LICENSE`, `NOTICE` and `CHECKSUMS.sha256`.

-## Limitations and known issues
+## Personal and sensitive information
+
+Some images show divers or aquarium visitors, and `fish-boxes` has `human` and `human divers` labels. Location fields (`lat`, `lon`) are null unless the source provides them.
+
+## Considerations and limitations
 
 - **Dropped rows.** 35 `coral-masks` images were dropped because no class map could be built (`reef-support-benthic-own`
   24 of 1,250, `reef-support-seaview-labels` 11 of 2,707). 12 `instance-masks` rows were dropped (`uiis` 6 of 4,628,
   `uiis10k` 6 of 10,048).
-- **Splits are not independently audited.** The mask configs were not near-duplicate checked, so near-identical frames
-  can fall on both sides of a split. `fish-boxes` ran a dedup gate. Seaview `split_group` (site partition plus the first
-  5 characters of the image id) is provisional.
-- **One image, several configs.** `instance-masks` and `fish-boxes` are built from the same UIIS, UIIS10K and USIS10K
-  images and are split per config. Join on `image_sha256` before evaluating across configs.
-- **Seaview masks are decoded from rendered colours.** They come from stitched RGB Labelbox renders with a fixed
-  5-colour palette (Hard Coral = 1, Soft Coral = 2, `0` = unlabelled).
+- **Splits are not independently audited.** The mask configurations were not checked for near-duplicates, so
+  near-identical frames can fall on both sides of a split. `fish-boxes` ran a deduplication gate. The Seaview
+  `split_group` (site partition plus the first 5 characters of the image id) is provisional.

+  USIS10K images and are split per configuration. Join on `image_sha256` before evaluating across configurations.
 - **Vocabularies differ per source.** `label_native` is the source's own label. The shared `taxon_node` and `coarse`
   mappings are partial and `coarse` is often null.
-- **People and context.** Some images show divers or aquarium visitors (`fish-boxes` has `human` and `human divers`
-  labels). Location fields are null unless the source provides them.
+- **Image provenance.** For the UIIS-family sources, image rights are described under [Licensing](#licensing).
+- **Geographic and habitat coverage** follows the sources (for example, the Coralscapes images come from Red Sea dive
+  sites) and is uneven. Models trained here may not transfer to other regions or imaging conditions.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+Mask encoding: semantic masks are `uint8` index PNGs (`255` = ignore); instance masks are `uint16` instance-id PNGs (`0` = background). Every row repeats its licence and attribution.

+## Notes
+
+- `reef-support-seaview-labels`: the images come from the XL Catlin Seaview Survey (CC BY 3.0, attribution in NOTICE); the masks are Reef Support annotations (CC BY 4.0). Masks were decoded from stitched RGB renders with a fixed 5-colour palette (Hard Coral = 1, Soft Coral = 2, 0 = unlabelled, ignore). `split_group` for these rows is the site partition plus the first 5 characters of the image id (provisional).
+- `reef-support-benthic-own`: Reef Support imagery and annotations (CC BY 4.0), source version 2026-09-24.
+- Rows were dropped where no class map could be built: 24 of 1,250 `reef-support-benthic-own` and 11 of 2,707 `reef-support-seaview-labels`.
+- The licence stated by the University of Queensland for the Seaview images is CC BY 3.0. The Seaview rows of this release read `CC-BY-3.0-AU` in their `licence` and `attribution` columns; the licence stated by the University of Queensland, CC BY 3.0, applies and takes precedence over the column.
+
+Changes made by Reef Support: images and masks were re-encoded into Parquet, `class_map` or `instances` were added, and splits and `split_group` were assigned.

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of

+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,

+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

-Mask encoding: semantic masks are uint8 index PNGs, 255 = ignore; instance masks are uint16 id PNGs, 0 = background. Every row repeats its licence and attribution.

+Reef Support Marine Data v1.0 (October 2026). Part of [reefsupport/marine-data](https://huggingface.co/datasets/reefsupport/marine-data).
+
+Underwater scene semantic segmentation from SUIM (8 classes including plants and seagrass, fish, reef, wrecks and divers): `image`, a `uint8` index `mask` and a per-image `class_map`.
+
+Splits are the upstream splits where the source provides them, otherwise a deterministic 80/10/10 hash of `split_group`. No near-duplicate check was run on this configuration.
+
+Mask encoding: semantic masks are `uint8` index PNGs (`255` = ignore); instance masks are `uint16` instance-id PNGs (`0` = background). Every row repeats its licence and attribution.
