PM Location: Slope off Saglek Bank (59° 26' 21.67" N, 59° 14' 38.78" W)
Sea Temperature: 8.1° C
Air Temperature: 8.3° C
Hydrospheric Conditions: Choppy conditions returned this morning about sea heights and swell increased through the day. One to two meter swells with small breaking waves persisted through the night.
Atmospheric Conditions: Cloudy skies with light rain continued off and on through the morning, ceased through the afternoon, and returned again at sunset.
Wind Speed/Direction: 14 knots/SE switched and increased to 30 knots/E

The CCGS Hudson and her team of Canadian Geologic Survey scientists have begun their journey back toward the southeastern coast of Canada. I've been logging some of the weather data recorded on the ship's Bridge each day and have displayed a set of this data in the table below. Based on the trend shown in the table, make a prediction of the changes you think we will observe in the air and sea surface temperatures based on the CCGS Hudson's upcoming changes in latitude. How will the air and sea surface temperatures change as we head southwest toward Halifax, Nova Scotia? Record your prediction and continue to log your own set of weather data to test your hypothesis at the end of the voyage.

Today's Activity: Before making your prediction on the air and sea surface temperatures, draw a graph illustrating the data above. HINT: Make the "Date" column your "X" axis and the "Latitude" column your "Y" axis. It will also be helpful to round off the latitude coordinates to a whole number.

Word of the Day: Geologic or Geology

REMINDER: Record today's Sea Surface Temperature (SST) and the Air Temperature on the data table you created from the August 05 journal.
