Data Tools

All data available through CIOOS Atlantic can be discovered, accessed and downloaded via the tools outlined below. Specialized open source tools have been implemented and new tools developed in order to make data usable to a wider audience. For each tool a brief description is provided, along with relevant links. Additional tools and functionality are continually under development.

Data Explorer

Use the map to search  geographically for data, across supported datasets. Filter, aggregate, and download just the data that meets your criteria. Data Explorer downloads are in a standardized (.csv) format.

Asset Map

The CIOOS Atlantic Asset Map allows access to the datasets available in our data catalogue using a simple map based interface.

Data Catalogue

Use filters and keywords to search the full collection of CIOOS datasets across Canada. You can use the catalogue to find the data or metadata in its original format, and many can be converted to a format that meets your needs.


CIOOS Atlantic employs an ERDDAP server to provide access to historic and real-time observations from the Atlantic Seaboard.

ERDDAP is a data server that provides a simple, consistent method to download subsets of scientific datasets in common file formats and to create graphs and maps.

Aquaculture Siting

As part of the Ocean Supercluster funded project – VITALITY: Leveraging CIOOS to Accelerate Industry, the Centre for Marine Applied Research (CMAR) and 3D Wave Design developed two 3D visualizations of generic aquaculture sites located in Nova Scotia. The 3D digital elevation visualizations display temperature data collected at various depths on a moored sensor string. Data was recorded using three sensors: Hobo Water Temperature Pro v2, Aquameasure DOTs, and VR2AR Acoustic Release Receivers. Maximum, minimum, and average temperature can be viewed for each depth using these visualization tools.

Birchy Head, St. Margaret’s Bay
Data collected from November 2019 to November 2020.

Ship Harbour
Data collected from February 2018 to May 2020.


The PhytoFit app allows visualization of satellite-derived chlorophyll-a concentration, extraction of time series and statistics for user-selected regions, and computation of phytoplankton bloom metrics. The app was developed and distributed, and is maintained, by the Satellite Ocean colour and Phytoplankton Ecology laboratory (SOPhyE) at the Bedford Institute of Oceanography (Fisheries and Oceans, Canada – Maritimes Region) to automate calculation of statistics and modelling blooms for DFO AZMP and AZOMP programs to ensure consistent results within the programs, and allow more experimentation with bloom fitting formulation and parameterization.
