The ability to make measurements of phosphate (PO 4 3– ) concentrations at temporal and spatial scales beyond those offered by shipboard observations offers new opportunities for investigations of the marine phosphorus cycle. We here report the first in situ PO 4 3– dataset from an underwater glider (Kongsberg Seaglider) equipped with a PO 4 3– Lab-on-Chip (LoC) analyser. Over 44 days, a 120 km transect was conducted in the no...

A low-cost Unmanned Aerial Vehicle is compared with those already available and the motivation for its development is established. It is targeted at ship-based science missions and potential applications are described including a specific science case to measure white capping in the deep ocean. The current vehicle includes a range of more than 1000 Km, carrying a payload of 2 Kg and it can be launched and recovered from a coas...
