PIER's Scientific Tools.

Research Vessels

PIER's primary research vessel is the R/V Malolo, a 46' custom made Newton that is equipped with dual John Deere diesel engines and has a range of over 500 miles.  The Malolo is capable of housing five scientists comfortably and has several amenities that help the team perform a wide range of studies.  The Malolo has a 30-foot harpoon plank for tagging swordfish, a Furuno side-scan sonar system for acoustic sampling, dive compressor and live fish hold for transporting specimens.  The vessel is the primary research platform for most of the PIER studies and is berthed in Oceanside Harbor, California.  





PIER also owns an 18' Boston Whaler Outrage that is used extensively for coastal studies along southern California.  The whaler provides the team with a rapid transport vessel as well as an ideal dive and sampling platform.  The Whaler is critical for the maintenance of PIER's acoustic array and used throughout the year on most of the PIER projects..
