The TROPICS constellation of five identical CubeSats provides nearly all-weather observations of tropical cyclones using a passive microwave spectrometer. Its Tropical Cyclone Intensity Estimate algorithm calculates Minimum Sea Level Pressure and Maximum Sustained Winds from brightness temperature perturbations in specific microwave channels. This validated data release starts in June 2023 for the constellation and August 2021 for the Pathfinder satellite.
A constellation of five small satellites provides nearly all-weather, high-temporal-resolution observations of tropical cyclones. The TROPICS Tropical Cyclone Intensity Estimate (TCIE) algorithm uses microwave brightness temperatures from specific spectrometer channels to estimate Minimum Sea Level Pressure and Maximum Sustained Winds. This validated data release starts in August 2021 for the pathfinder satellite and June 2023 for the full constellation.

Christmas Island, an Australian territory moving north at 7cm/year, sits on oceanic crust 5000-6000 meters deep. The Bureau of Mineral Resources (BMR) conducted a 28-day research cruise in 1992 to assess seabed morphology, sediment thickness, and offshore mineral resources like manganese nodules and crusts. This data was intended to inform seabed boundary negotiations with Indonesia.
