The ETSP2013 Cruise is a research expedition to the Eastern Tropical North Pacific aboard the Nathaniel B. Palmer that is occurring between June 23 – July 28 2013. An international team with members from five countries will be assembling to explore the dynamic ocean off the coasts of Peru and Chile. Our overall objective is to better understand the role that nitrogen loss processes play in ocean biogeochemical cycles. If that makes no sense, you are not alone in that thought! Read on and maybe we will be able to help explain our research.
