Aanderaa

Aanderaa was founded in the early 1960s by Ivar Aanderaa, whose instruments, developed with the Christian Michelsen Institute, made long-term deep-ocean current recording possible. In 1968 four current meters were deployed in the Weddell Sea; two were recovered five years later with 12,000 hourly records, then the longest time series obtained.

In 2005 Aanderaa Instruments merged with Bergen-based Data Instruments (founded 1975, originator of offshore crane safety monitoring), forming Aanderaa Data Instruments. The company was acquired by Nova Analytics in 2009, which became part of ITT in 2010, and became part of Xylem in 2011. A recent announcement states that Aanderaa has transitioned to ownership under Temda Holding AS, a Norwegian holding company, and continues to operate its headquarters and manufacturing in Bergen.
