dc.description.abstract | Ocean gliders are increasingly a platform of choice to close the gap between traditional
ship-based observations and remote sensing from floats (e.g., Argo) and satellites.
However, gliders move slowly and are strongly influenced by currents, reducing useful
battery life, challenging mission planning, and increasing pilot workload. We describe a
new cloud-based interactive tool to plan glider navigation called OceanGNS© (Ocean
Glider Navigation System). OceanGNS integrates current forecasts and historical data
to enable glider route–planning at varying scales. OceanGNS utilizes optimal route–
planning by minimizing low current velocity constraints by applying a Dijkstra algorithm.
The complexity of the resultant path is reduced using a Ramer-Douglas Pueckler model.
Users can choose the weighting for historical and forecast data as well as bathymetry and
time constraints. Bathymetry is considered using a cost function approach when shallow
water is not desirable to find an optimal path that also lies in deeper water. Initial field
tests with OceanGNS in the Gulf of St. Lawrence and the Labrador Sea show promising
results, improving the glider speed to the destination 10–30%. We use these early tests
to demonstrate the utility of OceanGNS to extend glider endurance. This paper provides
an overview of the tool, the results from field trials, and a future outlook. | en_US |
