The US GEOTRACES North Atlantic cruise aboard the R/V Knorr completed the section between Lisbon and Woods Hole that began in October 2010 but was rescheduled for November-December 2011.The NAT GT11 2011 cruise was conducted in the eastern North Atlantic Ocean. The aim of this cruise was to analyze low-level nanomolar nutrients through sampling for properties such as stable isotopes, dissolved inorganic carbon, radiocarbon, and so on. This cruise resumed the first U.S. survey section as part of a participation in the international program: GEOTRACES. In October 2010, the cruise began, departing Lisbon towards Mauritanea (towards Bermuda and Woods Hole), but problems with the ship’s propulsion system delayed the cruise in the Cape Verde Islands. The cruise was able to be resumed again in November 2011, but sailing in the reverse direction (Woods Hole to Bermuda to the Cape Verde Islands).
