This site is dedicated to VOACAP (Voice of America Coverage Analysis Program for HF Propagation Prediction and Ionospheric Communications Analysis), an improved and corrected version of IONCAP, retaining all of the theory as put forth by John Lloyd, George Haydon, Donald Lucas and Larry Teters in the 1975-1985 time-frame with modifications which were suggested/approved by George Lane, Donald Lucas, George Haydon and A. D. Spaulding (a world authority on HF radio noise predictions).

The U.S. Science Support Program (USSSP) facilitates involvement of the U.S. scientific community in the International Ocean Discovery Program (IODP). USSSP provides support for U.S.-based researchers to plan and participate in IODP expeditions on multiple drilling platforms. Among the activities supported by USSSP are thematic workshops, pre-drilling research, shipboard staffing and salary support, post-cruise studies, fellowships for graduate students, and an IODP-themed lecture series. USSSP staff also help the U.S. community communicate IODP-related research, participate in the IODP international advisory structure, and develop education products.
