Activity Report for the Period
January 12, 2001 - February 8, 2001
Trip Summary
During this period, there was 1 construction trip made on January 25 to place 19 manufactured Towers within fish
havens FH-1, FH-2, FH-12, and FH-13. The Towers measured approximately 5 feet by 5 feet by 10 feet tall. Steve
Rhodes was contracted to provide construction services and PRIMOFISH.COM provided Spotter Boat services.
010125a Towers 1-7 (ID=238F13)
Lat 30°01.296'N Lon 88°30.163'W TD's: 12471.8 47028.2 29630.5
There were 7 Towers placed here with the first four fairly concentrated together and the last three more spaced along a trail going
west. The surrounding depth was 81 feet, tide was at about 0.1 feet at 3PM, DGPS was tracking 10 Satellites with a hoop of 1.7
and accuracy of 14 feet. Minimum clearance depth is 70 feet.
010125b Towers 8-11 (ID=239F12)
Lat 30°02.300'N Lon 88°44.665'W TD's: 12314.9-0 47031.7 29478.3
There were 4 Towers placed here concentrated together. The surrounding depth was 42 feet. Minimum clearance depth is 31 feet.
010125c Towers 12-15 (ID=240F1)
Lat 30°03.902'N Lon 88°36.631'W TD's: 12406.0 47038.5 29596.1
There were 4 Towers placed here concentrated together. The surrounding depth was 61 feet. Minimum clearance depth is 50 feet.
DGPS Info had improved to 9' Accuracy, 1.2 Hoop, 9 Sats.
010125d Towers 16-19 (ID=241F2)
Lat 30°05.314'N Lon 88°34.376'W TD's: 12428.9-8 47044.3-2 29604.7
There were 4 Towers placed here concentrated together. The surrounding depth was 55 feet. Minimum clearance depth is 44 feet.
chart Discrepancies
It has been noticed that GPS charting that shows the fish havens boundaries show those boundaries incorrectly. MGFB's permits
are issued with LORAN coordinates for the boundaries and it is hypothesized that the charting companies are converting these
numbers mathematically to place them on the charts. Since these conversions are not accurate, there has been an ongoing effort
to obtain accurate LAT/LONG coordinates for the site boundaries. FH-2, FH-3, FH-4 and FH-5 were documented in the March 9,
2000 report. FH-7 was documented in the April 13, 2000 report. On this trip site boundaries were located for FH-1 and FH-6 with
LORAN and DGPS coordinates as follows:
FH-1 NE: Lat 30°03.92' Long 88°36.37' TD's: 12408.7 47038.6
FH-1 NW: Lat 30°03.94' Long 88°36.82' TD's: 12404.2 47038.6
FH-1 SW: Lat 30°03.02' Long 88°36.83' TD's: 12404.2 47034.9
FH-1 SE: Lat 30°03.00' Long 88°36.38' TD's: 12408.7 47034.9
FH-6 NE: Lat 30°02.09' Long 88°41.58' TD's: 12356.3 47031.0
FH-6 NW: Lat 30°02.09' Long 88°41.72' TD's: 12354.9 47031.0
FH-6 SW: Lat 30°01.89' Long 88°41.73' TD's: 12354.9 47030.2
FH-6 SE: Lat 30°01.88' Long 88°41.58' TD's: 12356.3 47030.2
