The Data and Sample Research System for Whole Cruise Information in JAMSTEC (DARWIN) offers comprehensive metadata on research cruises conducted by the JAMSTEC fleet and submersibles, including onboard measurement data. It also provides detailed information on samples collected during cruises and dives. Each cruise report, summarizing key data, is accessible through the cruise metadata. By integrating these resources, DARWIN serves as a centralized platform for accessing the full scope of JAMSTEC’s research cruise activities.
