IOC Sea Level Station Monitoring Facility

Use in your agent

Call the IOC Sea Level Monitoring Facility REST API into pandas. Checked against the provider's documentation on Nov 5, 2026.

Access

• Register as an API user at ioc-sealevelmonitoring.org/service.php to get REST web-service access.
• Non-commercial use only; commercial users must contact the relevant data originators.

Request

curl 'https://www.ioc-sealevelmonitoring.org/bgraph.php?code=STATIONCODE&output=tab&period=1'

Format

Per-station real-time sea-level value tables/graphs; registered REST API users get station metadata and data JSON per the Api Documentation linked from the Services page.

Load into pandas and Parquet

Needs Python 3 with requests, pandas and pyarrow.

"""IOC Sea Level Station Monitoring Facility: registered REST API -> pandas -> Parquet. Non-commercial use only; needs free registration."""
import os
import requests
import pandas as pd

API_KEY = os.environ["IOC_SEALEVEL_API_KEY"]
URL = "https://www.ioc-sealevelmonitoring.org/service.php"
r = requests.get(URL, params={"query": "stationinfo"}, headers={"Authorization": f"Bearer {API_KEY}"}, timeout=60)
r.raise_for_status()
df = pd.json_normalize(r.json())
df.to_parquet("ioc_sealevel_stations.parquet", index=False)
print(len(df), "stations")

Needs a personal, registered API key; not run.

Limits

• Non-commercial use only; commercial users must contact the relevant data originators per the disclaimer's data policy.
• Disclaimer states the real-time data "has not undergone any quality control and data is provided as received."

Quirks

• The public web view (no key) shows per-station graphs and tables; bulk/API access needs free registration as an API user.
• Long-term mean sea level (MSL) data is out of scope; it is served separately by PSMSL, BODC and UHSLC.
