Tow area

Hole area
Figure 3.5-3. Time series of representative REMOTS images obtained at Little Tow trawl station 3A
Figure 3.5-4. Time series of representative REMOTS images from Little Tow trawl station 1A showing
an absence of any significant changes in sediment physical or biological characteristics
attributable to trawling disturbance (similar to Figure 3-3)
Figure 3.5-5. Time series of representative REMOTS images from Mud Hole trawl station 3A
illustrating the continued persistence through time of Stage I polychaete tubes at the
sediment surface and a well-developed RPD, despite intensive trawling following the
August survey

illustrating the continued persistence through time of Stage I polychaete tubes at the
sediment surface and a well-developed RPD, despite intensive trawling following the
August survey
Figure 3.5-7. Two representative images from the October survey in the Little Tow area, showing a
lack of difference in sediment physical or biological features between control station 2C
and trawl station 3A
Figure 3.5-8. Two representative images from the November survey in the Mud Hole area, showing a
lack of difference in sediment physical or biological features between control station 2A
and trawl station 3A
