This scientific research will continue in 2000 and they need your help to make this historic effort a success. However, participants have a chance to win a grand prize trip by sponsoring a tag. This years Grand Prize is an all expense paid marlin fishing trip to Kona, Hawaii.
Bluefin tunas are one of the most valuable fish in the ocean today.
Unfortunately, we know very little about the bluefin tuna. The tags contain up to a year of data collected every two minutes on the bluefin tunas diving patterns, thermal biology and position on earth. Pressure sensor data indicate the bluefin tuna spend most of their time above 600 feet of water depth and considerable periods near the surface. However, they are capable of diving to depths of 2400 feet. Light data provides sunrise and sunset information that permits calculation of daily longitude and latitude.
