Operation of unoccupied aerial systems (UAS) from ships are proving to be an important modern sensing platform that advances oceanographic research and expands capabilities of ocean observing systems. For over a decade, 我的 group at Lamont-Doherty Earth Observatory has worked to develop an infrastructure design of and laid the foundation for a revolutionary new UAS platform and sensor payload capability to support state-of-the-art oceanographic and atmospheric research with unparalleled flexibility of tasking. Here, we present the development of cutting-edge payload instrumentation for UASs that provides a new capability for ship-deployed operations to capture a unique, high resolution spatial and temporal variability of the changing air-sea interaction processes than was previously possible. The ship-based Remote Aerial Vehicle Exploration Network (RAVEN) consists of five components: (1) a fleet of fixed-wing high-endurance (>12 hour) UASs with a fully-autonomous Vertical Take-Off and Landing (VTOL) capability; (2) a high-bandwidth (100+ Mbps at 50 nautical miles), networked real-time communication system for active mission control from the research vessel to act as our “eyes over the horizon,” (3) modular interchangeable scientific payloads (15-lb nominal), (4) advanced mission planning software, and (5) a streamlined data archiving pipeline. The RAVEN facility infrastructure enables novel scientific research, meets the diverse needs of the oceanographic community by filling an important gap in existing oceanographic infrastructure, and provides the next generation of instrumentation capability for integrated ship-based UAS research. Ultimately, our goal is to make UAS technology and observations as routine onboard research vessels as the CTD, yet the limits of their utility are as boundless as the imagination of the instrument’s users. When deployed from research vessels, UASs provide a transformational science prism unequaled using 1-D data snapshots from ships or moorings alone, and improve asset mobilization for targeted efficient data collection. In this talk, we will take a virtual ride of discovery on an unoccupied aerial vehicle from the Pacific Ocean near Fiji all the way to a coastal village in the Arctic. In 2016 and 2019, we flew the Latitude model HQ-90 fixed wing UAS from the R/V Falkor in the Western Pacific 400 nautical miles south of Guam (2016) and Fiji (2019) to study processes of the sea surface microlayer and their effects on upper ocean heating, radiance and irradiance. We continued our work in 2018 and 2019 with UASs in the Arctic bridging the scientific and indigenous communities to study sea ice change in Alaska with funding from the Moore Foundation. We will discuss topics ranging from the bio-physical processes that impact a warming ocean, to understanding the impacts of a changing climate on 日e subsistence living of indigenous communities in Alaska.
