Science data and results

Ensuring that our scientific research, data and results are produced and disseminated in an open, timely and transparent manner is essential to successfully fulfill our science mandate.

Field program results are communicated through technical and data reports available on:

Nautical charts, navigational products and survey results can be accessed from the Canadian Hydrographic Service.

Every September, we publish a technical report on the State of the Pacific Ocean presenting results of the most recent year’s monitoring information about the state of the physical, biological and selected fishery resources of Pacific Canadian marine ecosystems.

2024 to 2025 science datasets

The following science datasets were published or updated on the Open Government Portal from April 1, 2024 to March 31, 2025 and highlight our scientific activity throughout the year. Many of these datasets used results from Pacific field operations.
