<div>Hi Deb,</div>
<div><br>
</div>
<div> In response to your first question, at OSM it was mentioned that the TMC rosette would not sample waters shallower than about 20m. If this is still the case, we will definitely need the use of the TMC towfish for sampling above this depth and for some
larger volume-demanding measurements (e.g. RNA). Thus having the towfish accessible in close coordination with the TMC rosette casts may be critical for a number of groups including mine. I realize at one point in time we discussed simply collecting mixed
layer waters at the shallowest depth the TMC rosette was able to go (about 20m) but the issue is that there might easily be times when the mixed layer at St. P is as shallow as 10m or so (see Figure 1 in attached paper). If this is also the case during EXPORTS,
this would mean ALL of our mixed layer water samples would need to be collected by the towfish.</div>
<div><br>
</div>
<div>Something we will for surely need to continue to discuss.</div>

Dear all,
<div class=""><br class="">
</div>
<div class="">Thanks for your responses last week.</div>
<div class="">A few more things I need some feedback on:<br class="">
<div class=""><br class="">
<div class="">1) Can you please let me know if you anticipate wanting to use the trace metal clean towfish for collecting large volumes of surface water? Right now we are looking at using the towfish twice on the cruise, for setting up Bethany Jenkin’s two
grow-out experiments; if others are also interested in this surface water for other experiments, we can try to time these efforts to coincide (or possibly schedule in some additional deployments).</div>
<div class="">I just need a general sense now how often this instrument might be deployed, because we have a crunch on starboard instrument deployments. </div>
<div class="">Please know that regular collection of TMC surface water samples will now be done with the TMC rosette.</div>
<div class=""><br class="">
</div>
<div class="">2) Right now we still have an extra winch (Poseidon) reserved in the equipment pool- just in case. But SIO would like to release it because there is a lot of other demand out there. If anyone out there anticipated using another winch for something,
please let me know. </div>
<div class="">*Emmanuel- my understanding is the slow drop IOP package will be deployed with the crane off the stern, and a tugger (with TSE winch…I think) will be used to bring it back on board. So do not need extra winch. I will confirm this with Matt Durham.</div>
<br class="">
3) I have not heard from anyone requesting strobes or a radio detection finder, so I will assume not needed (unless I hear by today that you either do, or are still trying to figure it out).</div>
<div class=""><br class="">
</div>
<div class="">thanks,</div>
<div class="">Deb</div>
