+# Dataset Card for NOAA-ESD-CORAL-Bleaching Classification Dataset v1
+
+## Overview
+
+For the development of machine learning models to classify coral health, specifically identifying **healthy hard coral (CORAL)** and **bleached hard coral (CORAL_BL)**.This dataset contains underwater imagery collected by NOAA's Ecosystem Sciences Division (ESD) and other benthic surveys. 
+### Labels
+
+| Label    | Name                 | Functional Group |
+|----------|----------------------|------------------|
+| CORAL    | Healthy Hard Coral    | Hard Coral       |
+| CORAL_BL | Bleached Hard Coral   | Hard Coral       |
+## Dataset Details
+
+### Dataset Description
+- **License:** Public Domain ([NOAA Open Data | Public Access](https://data.noaa.gov/))
+- **Curated by:** Ecosystem Sciences Division (ESD) | Pacific Islands Fisheries Science Center (PIFSC)  
+- **Image Size:** 224 x 224 pixels (patch-based)  
+- **Total Images:** 10,419  
+- **Splits:**  
+  - Training: 7,292 images (70%)  
+  - Validation: 1,562 images (15%)  
+  - Test: 1,565 images (15%)  
+
+Images were annotated through a combination of **randomly generated points** and **targeted survey locations**.
+
+## Dataset Structure
+
+The dataset consists of **224x224 pixel image patches**, pre-split into train, validation, and test sets. Patches are sampled across **2 rows x 5 columns** stratified grids for consistent annotation coverage.
+
+| Split      | Images | Description                        |
+|------------|---------|------------------------------------|
+| Training   | 7,292   | Used for model training.           |
+| Validation | 1,562   | Used for model hyperparameter tuning and early stopping. |
+| Test       | 1,565   | Used for final model evaluation.   |

+## Dataset Sources
+
+- **Data Repository:** [NOAA Open Data Dissemination (NODD) PIFSC Cloud](https://console.cloud.google.com/storage/browser/nmfs_odp_pifsc/PIFSC)  
+- **Imagery Collection Years:** 2014–2019  
+- **Region:** Hawaiian Archipelago  
+

+
+## Uses
+
+### Direct Use Cases
+- Coral bleaching detection in marine ecosystems.  
+- Marine biology research and reef health assessments.  
+- Training machine learning models for underwater imagery analysis.  
+
+### Out-of-Scope Uses
+- Applications unrelated to benthic or coral reef ecosystems.  
+- Real-time monitoring without adequate validation or ground truth verification.  
+
+---
+## Bias, Risks, and Limitations
+
+### Bias
+- **Geographic Bias:** Data is primarily from the Hawaiian Archipelago; performance may differ in other regions.  
+- **Environmental Bias:** Imagery collected under certain lighting and seasonal conditions.  
+
+### Recommendations for Use
+- Validate models on new survey data before operational use.  
+- Augment datasets with **color variations, rotations, and noise** to improve robustness.  
+- Account for potential false positives, especially in complex benthic environments.  
+
+### Limitations
+- Models may underperform on color images if trained solely on the provided dataset.  
+- **Bleaching classification** may be affected by turbid water conditions and image quality variations.
+
+### Personal and Sensitive Information
+- No personal, sensitive, or identifiable information is present.  
+- Images are of **marine environments** only.
