    Backward Drifters from Port Aransas during HAB Times Tracking drifters

    backward from Port Aransas from the autumn into summer helps indicate their origin Kristen M. Thyng (Texas A&M) Harmful Algae 2013 October 29, 2013 4 / 6

    Forward Tracking from the South Limiting drifters to those near

    Port Aransas during fall shows that drifters in non-HAB years hit the coast or exit the domain before the critical time. Kristen M. Thyng (Texas A&M) Harmful Algae 2013 October 29, 2013 5 / 6
