2024-25 Casey ASPA 135 ANTOS data collection using SAEF AIoT Prototype 1.5 platforms

Casey 24/25 deployment of two SAEF Artificial Intelligence of Things (AIoT) Prototype 1.5 platforms for data collection in ASPA 135 at Antarctic Nearshore and Terrestrial Observing System (ANTOS) monitoring sites. Field logistic support by AAS 4644 (ANTOS) using smart sensing platforms developed under AAS 4628 (SAEF; SR200100005).Two AIOT v1.5 units deployed in ASPA 135: Box 1: ASPA 135 – selected ANTOS tower site (camera facing moss site)Location: 110.538867809103, -66.2828989690345External thermocouples measured soil surface (few mm under surface)Box 2: Long-term vegetation monitoring site (camera facing east)Location: 110.538288974015, -66.2818963416407External thermocouples measured inside branched structure of Usnea lichens (above soil surface) Each unit included an array of sensors and an onboard camera.
