Storage Notes:


Will you be using Long Base Line (LBL) navigation? no

Will you be using Ultra-short baseline (USBL) navigation for other than Alvin operations? no

Navigation Notes:


Other Portable Winch

Winch Notes: We need a lightweight winch and a suitable block for our sediment net traps deployments, which are < 200 lbs in air.

Wire use and application

CTD Winch with .322" Electro-mechanical wire

Wire Notes: In addition to the wire for the CTD, we need the 3/8" hydro wire to hang McLane pumps from.  These pumps are in the neighborhood of 100 lbs each in air, and we may hang a half dozen.
