day4 – she’s here

all personnels, all instruments, there’s sea-ice floating near Bering Strait according to reports. We’ll be on the look-out for both sea ice and walrus! (“where there’s seaice there’ll be walrus” as our expert puts it.) see you all in 2 weeks!

day2 – assembling

today was spent assembling all the instruments we tuned the previous day, putting them into frame, adding buoys, re-packing the containers. all preps are nearly done as we sit tight waiting for news from the ship. Things are beginning to make sense to me now as far as instruments are concerned. As advertised, the gumby suit fitting was hilarious :-). and as always, a tune-in-the-head for the day, no clue what’s sung, but i love the melody.

day1 – calibrating

this never ending daylight in combo with different timezones on all of our laptops are confusing big time, not that i’m complaining! we’re just south of the arctic circle here. today was spent unpacking most of the delicate instruments from the shipment containers at the dock and calibrating to make sure everything functions as hoped. We got divided into group so i only know mainly the ADCP instrument. That’s for measuring the ocean speed and direction.
In addition, we also calibrated the CTD instruments, though i was stuck with trying to get the satellite phone to do ftp (unsuccessfully) so can’t tell you much how exactly to turn on/off/calibrate the CTD. Those (CTD) provide temperature and salinity of the water (most important for oceanographers). Seen above is the recorder (record info from the CTD). Lastly there’s also ocean bottom pressure sensors to give you information about the water column depth, i.e., instead of measuring “depth”, we can measure the weight of the water above the instruments and infer depth from that. Tomorrow plan: “building” instruments! i quite looking forward! and here’s the tune-in-the-head of the calibrating day.

(ps- oh, during dinner, i just found out those anchors are train wheels! They each weights ~ 1800lbs and we need about 2 of them to hold the instruments in place against the very strong currents across Bering Strait.)
