This project continues our development of innovative systems for farming macroalgae on the
high seas. We will identify suitable sites in Nantucket Sound to demonstrate our system and
determine the associated environmental parameters including depths, currents, and waves. By
combining that information with load and acceleration data from our Phase I wave-basin tests,
we will refine the structural details of a two-transverse-truss array for fabrication and
deployment. This 33m x 67m, instrumented, array in will support 36 seeded longlines of sugar
kelp, Saccharina latissimi. We will monitor the performance of the system and the growth of the
kelp at variable longline spacing from November 2017 to May 2018. We will harvest the kelp
and determine optimal longline spacing based on the goal of maximizing production per unit
area. A second season of kelp farming will then be used to measure optimized growth per unit
Using data collected from these instrumented sea trials, we will design a 100m x 200m array
that supports the culture of 2 ha of macroalgae longlines. Based on the projected system cost
and the productivity of our test crops, we will refine our profit/loss models for 2 ha array modules
and refine our business plan.
