This is the seventeenth posting of my trip to the icy continent. The others can be found in my blog at Link: http://goantoantarctica.blogspot.com
We are heading home with the accompanying crashing, banging and ice breaking. On the last day of science we sample the deep waters - up to 3000 meters. Accompanying this deep cast is the traditional Day of Cups - a tradition which like Thanksgiving and Christmas starts off with a lot of excitement and preparation and ends with leaving people deflated and with stuff they don't know what to do with. Let me start with the CTD, the darling of oceanographers. A huge circular frame is wired with sensors that measure Conductivity, Temperature, and Depth (hence CTD) and the frame is lowered via a winch. The sensors send back data profiles to the ship's computers giving the scientists an idea of the structure of the water column that they will be sampling. Attached to the frame are huge tube-like structures of PVC with lids on both sides. When the CTD is launched all the lids are left open but as it descends they can be triggered through computer controls to close at discreet depths . In doing so we are able to collect water from a particular depth with the least bit of disturbance. When the CTD comes to the surface everyone rushes to bleed it - this is the place where egos clash and greed for water surfaces. It gets ugly especially when people haven't slept in days. As we all know pressure in the water column increases by one atmosphere for every 10 meters which is not a big deal until on the Day of Cups. On this day every scientist equipped with an assortment of markers spends hours painting the polystyrene cups with colorful designs for their family and friends. The Day of the Cups on the Nathaniel Palmer dawned with a raid on the stationery closet and an attack on Lorenzo the chef who holds the polystyrene cups. Dormant cubists, surrealists and pointillists rose to the occasion as did patriots with flags on their cups. The cups were placed in a mesh bag and tied to the bottom of the CTD. Yes you have guessed it! When the cups reach lung bursting pressures they shrink into little sake cups and along with it shrinks your art work and the poem to your girlfriend. It's hard to tell which is greater - the pressure to be creative or the pressure of the water column. Two hours later when the CTD returned many had a fine set of shrunken cups but few knew what to do with them. Joaquim's cup said Antarctica-Goa and had coconut trees on it which the pressure had transformed into tiny hairy spiders. My cup from last year holds Canadian coins which I often find in my change. Someday when it's full I plan to visit Canada and buy a lucky goanetter a beer. -------------------------------------------------------------------------- | Goa - 2005 Santosh Trophy Champions | | | | Support Soccer Activities at the grassroots in our villages | | Vacationing in Goa this year-end - Carry and distribute Soccer Balls | --------------------------------------------------------------------------
