Sammendrag
The One Ocean Expedition (OOE) was a 20-month long circumnavigation of the globe by the Norwegian sail training vessel Statsraad Lehmkuhl, and a recognised part of the UN decade of Ocean Science for Sustainable Development. The ship was equipped with modern instrumentation to collect high-quality data on ocean physics, chemistry, and biology. Many of the data series were available in near real time from an open repository. The scientific programme was executed along the sailing route of Statsraad Lehmkuhl, with occasional stops for stationary work. The aim of the data collection on board the vessel was to improve knowledge about the state of the world's ocean with regards to the distribution and diversity of organisms, environmental status, climate, and human pressures on the marine ecosystem. Another aim of the expedition was to educate ocean scientists and strengthen ocean literacy. The main types of instrumentation are sensors that measure continuously underway including echosounder, hydrophone, temperature and salinity probes, and various instruments that collect and analyse water sampled from an inlet in the ship's hull, including for environmental DNA and microplastic. Here, we describe the scientific instrumentation onboard Statsraad Lehmkuhl and present preliminary results from the Atlantic part of the expedition. While there are many challenges to using a sail ship for scientific purposes, there are also some key benefits as the vessel is quiet and has a low footprint. Furthermore, the use of a common set of instruments and procedures across the ocean also removes an uncertainty factor when comparing data between ocean areas.
