also operates a site on mainland Miami-Dade County that was formerly the United States Naval Observatory Secondary National Time Standard Facility, which already had buildings and a 20M antenna used for Very Long Baseline Interferometry (VLBI). Rosenstiel School's Center for Southeastern Tropical Advanced Remote Sensing (CSTARS) and Richmond Satellite Operations Center (RSOC) have research facilities located on what is now named the Richmond Campus. In the 1990s, the school hosted the Miami Hoshuko, a part-time Japanese school for Japanese citizens and ethnic Japanese people in the area. While there, Miami Hoshuko used ten classrooms, a library, and a cafeteria facility. Research As of 2008, the University of Miami's Rosenstiel School receives $50 million in annual external research funding. Laboratories at Virginia Key are equipped with specialized instruments including a salt-water wave tank, the five-tank Conditioning and Spawning Systems, multi-tank Aplysia Culture Laboratory, Controlled Corals Climate Tanks, and DNA analysis equipment. The Richmond Campus' CSTARS provides Rosenstiel School with a near-real-time weather satellite downlink. Rosenstiel School also operates Bimini Biological Field Station, an array of oceanographic high-frequency radar along the U.S. east coast, and its Bermuda aerosol observatory. Research projects at Rosenstiel School are in the domain of atmospheric and marine sciences and include: Coral reef research, focusing on corals survival in a new climate conditions; coral reef protection Field programs evaluating trace gas chemistry and transport The aquaculture program Climate change modeling Tropical weather, climate, and atmospheric/oceanic circulations Air-sea interactions research through buoys, remote sensing, analysis in situ, a wave tank laboratory, numerical modeling; Volcanoes in the Pacific, Everglades water level measurements and subsidence through satellite images Studies of coastal quality and their impact on human health. Rosenstiel School's Marine Affairs and Policy Division conducts archaeological and paleontological research at Little Salt Spring in Sarasota County. The site was donated to the University of Miami in 1982. Rosenstiel School also hosts the National Center for Coral Reef Research (NCORE), which works to understand, conserve and manage coral reefs worldwide. Rosenstiel School has focused significant resources to studying the Deepwater Horizon oil spill and its long term environmental effect. The school is an active member of the State of Florida's Oil Spill Academic Task Force that works with the Florida Department of Environmental Protection on spill issues. In the summer of 2010, a CIMAS team working with the research vessel Walton Smith was able to document a long oil plume extending
