| Abstract | The Continuous Plankton Recorder (CPR) survey is one of the longest running marine biological monitoring programmes in the world. Started in 1931 by Sir Alister Hardy, the survey uses mechanical
samplers, which collect marine plankton on a moving band of silk, towed behind "vessels of opportunity". Today the CPR survey is operated by the Sir Alister Hardy Foundation for Ocean Science (SAHFOS), located in Plymouth, UK, and operates 21
sampling transects, at monthly frequency, across the global ocean. Uniquely, the CPR survey's methods of sampling and plankton analysis remain unchanged since 1948, providing a spatio-temporally comprehensive 70+ year record of marine plankton
dynamics. SAHFOS monitors the pulse of the oceans through the plankton and contributes to the significant scientific effort that advises political decisions on a global scale.
Biannually, SAHFOS produces the Global Marine Ecological Status
report, which provides a synopsis on the state of change in marine plankton dynamics in the world's oceans. As part of the AtlantOS project (https://www.atlantos-h2020.eu) and to make our data more discoverable, we undertook to translate the North
Atlantic section of this report into an interactive web-based product. The primary motivation for this is to make the hardcopy visualisations provided in the Global Marine Ecological Status explorable to end-users, and the underlying data accessible
by direct download.
The web project (http://192.171.193.51/sahfos demo/web-viz.html) is based on a GeoServer instance, providing both base maps and geographic features. The application uses OpenLayers 3 to make WMS and WFS requests to GeoServer.
Over the base map, we overlay 41 "CPR Standard Areas". These are approximately rectangular in the open ocean, but roughly conforming to the continental shelves inshore, and with coastlines constructed from NOAA's "Global Self-consistent,
Hierarchical, High-resolution Geography". Users can select one or more areas and a date range, and the type of charts to be shown.
Upon selection, the corresponding vessel routes and sample locations are dynamically overlaid on the map and, at
the same time, "heatmap" charts for the user-selected variables are displayed. The charts are generated purely in Javascript using Plotly.
Once displayed, the users may then choose to download any of the charts, or the data used to produce the
charts as a spreadsheet.
In the future, we plan to add visualizations for all of SAHFOS's standard products, adding maps for monthly means of Phytoplankton Colour Index, Total Diatoms, Total Dinoflagellates, and Total Eyecount Copepods, with the
ability to display these as an animation over time. |
