R/V Oceanus Cruise 218 (OC218) departed Woods Hole March 20,1990 for 20 days of work in a Gulf Stream Warm Core Ring. The scientific objective of the Warm Ring Inertial Critical Layer Experiment (WRINCLE) was to study the phenomenon of inertial-internal wave trapping in anticyclonic rings and the associate mixing. High Resolution Profiler (HRP) casts provided fine- and microstructure data and the Richardson Number float and eXpendable Current Profiler (XCP) surveys provided velocity and density finestructure measurements. During the time R/V Oceanus was in and around the ring, 78 HRP drops to 1000 m were completed, and data from 55 XCPs, 26 Conductivity Temperature and Depth Profiler (CTD) casts, and 59 eXpendable BathyThermograph (XBTs) were logged. The free-drifting Richardson Number float (RiNo) acquired data for eleven days in ring center. This report documents the work performed at sea, and summarizes some of the data collected.

Colonies were found on 98% of epipelagic diving stations in the period ...
