R/V New Horizon

Background

Scripps Institution of Oceanography's R/V New Horizon was used during the two weeks of MUSE to deploy drifters, gather data about the iron influence during upwelling events, and pull an undulating towfish to gather salinity, temperature and optical data.  

Natural Iron Enrichment
Occurring to a measurable extent in coastal upwelling zones, certain processes control the transformation of resuspended iron into bioavailable iron.  The "natural iron enrichment experiment" looked at the entrainment in upwelled water of iron-rich sediment from the continental shelf.  This iron is important to phytoplankton growth, but only two previous experiments have tracked it.  
Continuous measurements of particulate and dissolved iron were made from an ultra-clean seawater intake towfish aboard the R/V New Horizon during the period of August 19-31. Dissolvable iron concentrations were measured continuously at the sea surface and particulate iron concentrations were determined daily near the drifter.  
Other measurements taken from the New Horizon included ADCP currents, fluorescence, salinity, and temperature from an underway CTD (UCTD) and a separate profiling CTD (PCTD).  The R/V New Horizon has a permanently installed RD Instruments RD-VM series acoustic doppler current profiler. It is mounted to the bottom of the hull just forward of amidships and to starboard of the centerline. The system utilizes the doppler effect to measure currents in the water column. Current profiles can be produced in up to 128 depth cells, each cell being variable from 1 to 32 meters, to a maximum depth of 700 meters. When the bottom is within range an earth-referenced vessel velocity can be obtained which allows for measurement of currents in absolute terms. Data are processed on an IBM compatible PC. The system takes inputs from the ship's gyro compass and a Trimble 10X GPS/LORAN-C navigation receiver.
A Seabird SBE-21 Conductivity Temperature sensor was mounted on the R/V New Horizon. It accurately determines sea surface temperature and conductivity from underway vessels.
