  1. Seaglider: autonomous underwater profiling glider • Quick facts: • Buoyancy driven profiling • Roll & pitch controlled by battery movements • Max depth: 1000 m (for this model) • Endurance: up to 10 months • Modular sensor system – can add/remove easily • Built by Kongsberg, designed by University of Washington

  2. Seaglider: autonomous underwater profiling glider Diving profile: • Near real-time data transfer • Vertical speed ~10 cm/s • Each 1000 m dive: • 5 hours • 5 km on the surface

  3. Seaglider: autonomous underwater profiling glider • Sensors: • Can be easily added/removed • Our glider(s) have sensors for: • Temperature/Salinity • Dissolved Oxygen • Photosynthetically Available Radiation • Fluorometer/turbidity • (Acousonde – Acoustics) • Sampling interval can be 1-2 s • Other sensors are available and being developed

  4. Seaglider: autonomous underwater profiling glider Previous deployments at University of Gothenburg: Drake Passage Nov 2017 – Feb 2018 Glider was also equipped with an acoustic sensor to measure wind speeds. ROAM-MIZ (60°S, 0°E) Dec 2018 – Mar 2019 www.roammiz.com Upcoming deployments include a winter-time mission in the Southern Ocean, July 2019

  5. Seaglider: autonomous underwater profiling glider Temperature data from the ROAM-MIZ project: Colour shows the temperature measured, the black dots show the base of the mixed layer (surface layer where properties are homogenous). See more at www.roammiz.com
