John K. Hall (born 1940) is an American-born marine geophysicist, known for his work in marine geology, bathymetric mapping, and Arctic research. 
He is known for development of digital terrain models (DTMs) and bathymetric surveys for various regions of the world. He has also led work in bathymetric charting of the Mediterranean, Black Sea, and Arctic regions, as well as in the National Bathymetric Survey of Israel. In 2020, he was awarded the Medallion of the Israel Geological Society.
Early life.
Hall was born April 14, 1940 in Waltham, Massachusetts. He earned a Bachelor of Science degree in Geology from Rensselaer Polytechnic Institute (RPI) in Troy, New York, in 1962. He then completed his Ph.D. in Marine Geophysics at Columbia University’s Lamont-Doherty Geological Observatory (LDGO) in 1970, where he conducted research on the Arctic Ocean, including studies of the Alpha-Mendeleev Ridge.
Career.
Hall began his professional career as a marine geophysicist at the Woods Hole Oceanographic Institution (WHOI) before moving to Israel in 1970. He became the first marine geophysicist at the Geological Survey of Israel (GSI), where he established the Israel National Bathymetric Survey. 
Throughout his career, He was involved in the compilation of bathymetric data for various international projects, including the International Bathymetric Chart of the Mediterranean (IBCM) and the General Bathymetric Chart of the Oceans, where he contributed to the Mediterranean Sea bathymetry. 
He also collaborate with University of Haifa and the University of New Hampshire's Center for Coastal and Ocean Mapping (UNH-CCOM), to furthered advancements in marine geophysics and geoinformatics. 
He co-founded the Neev Center for Geoinformatics at the Hebrew University of Jerusalem (HUJI) in 2011. Hall also developed the first digital terrain model for Israel.
Hovercraft R/H Sabvabaa.
Hall is also the owner of the research hovercraft R/H Sabvabaa, which he funded and designed the construction of in 2007 with Yngve Kristoffersen of Norway’s Bergen University. In recent years, the hovercraft has been involved in Antarctic research, where it continues to support scientific exploration of remote ice-covered marine environments.
Awards.
Hall received the Israel Geological Society Raphael Freund Prize in 1999 and the Israel Cartographic Society Prize in 2004.
