| Objectives | During JR184 three stand alone ARPs were recovered, no unit was redeployed and 3 units refurbished. The units will be redeployed during JR 185. On arrival at FIPASS the despatched Cornell University cargo was available in Stanley office but it was not labelled properly. The concrete blocks where not organised and we had to get them delivered to the ship. An old net was provided to wrap 4 concrete blocks and 6 m of rope where attached.
Having probably been pulled up by a long liner, the mooring was found floating by the fisheries patrol vessel Pharos and stored at FIPAS, Stanley. Upon collection the mooring was inspected for damage and all instruments seemed to be in good condition. Close inspection showed the CTD had worked fine, however, the ADCP unfortunately hadn't due to a corroded connector. Before redeployment this connector was replaced together with batteries and all the hardware bits (shackels, ropes, cyclinks, chain) and CTD data was uploaded. Shallow water mooring was then successfully redeployed at 11:12:00 11/11/2007 @-53.80065S and-37.93695 W. The deployment took place as described in the second deployment report in JR96, with the changes described in the JR100 mooring cruise report: To control the release of the weights, they were lowered over the stern with the starboard Effer crane on a strop and a sacrificial rope attached to the weights was threaded through two deck eyes. The weights were then lowered down until the sacrificial rope took up the weight. Then the strop was taken of. At the release point the rope was cut on top of a piece of wood between the eyebolts using a knife. The CTD has worked fine all the time, the ADCP stopped working very shortly after the deployment, due to a corroded connector. The Western Core Box (WCB) survey was conducted between 7th and 10th of November 2007. The acoustic survey was run from west to east starting at the northern end of Transect 1.1 at 08.11 GMT. Detailed operating instructions of the ships echo sounder (EK60) can be found in the WCB survey protocol, current version 2.0 from December 2006. The EK60 was run continuously throughout the cruise with a 2 second ping rate and data logging was continuous. The weather this time was exceptional good, with calm seas throughout the survey. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
