PANGAEA Data Repository API

Overview

PANGAEA is the world's leading data repository for earth and environmental sciences, hosting 400K+ datasets with 20B+ data points. It archives research data from oceanography, paleoclimatology, geology, ecology, and atmospheric science. Each dataset has a DOI and is linked to the originating publication. The API provides search, metadata retrieval, and data download. Free, no authentication required.

API Endpoints

Search API

# Search datasets by keyword

curl "https://www.pangaea.de/advanced/search.php?\
q=sediment+core&minlat=-60&maxlat=-30&minlon=-180&maxlon=180&type=json"

# Filter by parameter (measurement type)
curl "https://www.pangaea.de/advanced/search.php?\
q=carbon+dioxide&param=Atmospheric+CO2&type=json"

# Filter by date range
curl "https://www.pangaea.de/advanced/search.php?\
q=Arctic+ice&mindate=2020-01-01&maxdate=2026-12-31&type=json"

ElasticSearch API

# Full-text search via Elasticsearch
curl -X POST "https://ws.pangaea.de/es/pangaea/panmd/_search" \
  -H "Content-Type: application/json" \
  -d '{
    "query": {
      "bool": {
        "must": [
          {"match": {"citation.title": "ocean temperature"}}
        ],
        "filter": [
