Science and Technology Log
The seas are still very rough with 40 knot winds. No fishing trawls due to the high waves and heavy seas. However, despite the rough seas, we were able to conduct an XBT, which stands for Expendable Bathythermograph. An XBT is a measuring apparatus consisting of a large lead weight connected to a very thin copper wire. The function of the XBT is to measure the temperature throughout the water column. It is launched off the stern (back) of the ship. As it sinks to the sea floor, temperature data is transmitted to an onboard computer.
The Miller Freeman is an NOAA research vessel. Here’s a bit of information about the Miller Freeman…For more information go here. The Miller Freeman is a 215foot fisheries and oceanographic research vessel and is one of the largest research trawlers in the United States. Its primary mission is to provide a working platform for the study of the ocean’s living resources. The ship is named for Miller Freeman (1875-1955), a publisher who was actively involved in the international management of fish harvests. The ship was launched in 1967, but not fully rigged until 1975. The vessel was again re-rigged in 1982. Its home port is Seattle, Washington. It is capable of operating in any waters of the world. The ship has 7 NOAA Corps officers, 27 crew members, and maximum of 11 scientists.
Following is a “tour” of the ship. It has many nice amenities for extended life at sea.
The Gift of Patience
Wending our way through the North Pacific Ocean,
The massive waves crash against our hull with Herculean strength
As high as a one story building, their tops are dolloped with luscious whipped cream
They take their turn crashing against the ships sturdy hull, as gale force winds whip wildly past.
We play a waiting game. We practice the ancient art of patience.
When will we have hake, the silvery, slender fish that evades our sonar?
As the winds blow, cold sea spray stings my face.
I watch as the never ending line of waves wait their turn to hit the ship’s hull.
The waves wait patiently as do we.
The sea teaches us serenity.
We must not show greed or impatience.
The sea will provide.
One should lay empty and open waiting for the gifts from the sea.
