1. Cruise Planning

2. Why? Doesn’t the PI do all the planning? –Overall – Yes –The tech may be call upon to help plan sensor setups –Up to the tech to actually do the deployment

3. Cruise Track Where are you going to sample? –Station Locations Do Not use GoogleEarth!! –GPS coordinates are not always accurate –Does not do water depths Use a charting program –NOAA »Free programs and charts MatLab works for gridding stations –Still would plot on a chart to help with depths

4. GPS Positions Positive is North and East Negative is South and West Types of Positions –Degrees Minutes Seconds (DMS) 30 0 22’ 26.60”N x 89 0 36’ 46.22” W 30 0 22’ 26.60” x -089 0 36’ 46.22” –Degrees Minutes.m 30 0 22.4433N x 89 0 36.7703W 3022.4433 x -08936.7703 –Decimal Degrees 30.37405 x 89.612838

5. GPS Positions Universal Transverse Mercator (UTM) –Define two dimensional, horizontal positions –Divided the earth into Zones Zone number designate 6 degree Longitude strips from 80 0 South latitude to 84 0 North latitude Special zone between 0 0 and 36 0 longitude above 72 0 latitude Special zone 32 between 56 0 and 64 0 north latitude –Easting is measured from Central meridian –Northing is measured from Equator

8. What type of position do you need? –Degree Minutes.m Captains will make you go convert

9. Cruise Track Do not plan track on ships max speed Be prepared to alter track –Weather causes delays –Sampling takes longer at each station What are the drop stations –Maybe just need to cut what you sample at some stations
