ALT Three graphs with latitude on Y axis (60 deg North to 60 deg S). Left graph: Pacific Ocean temp in deg C (X axis) with latitudinal temperature gradient shown from dark blue to dark red circles. Right graph: Atlantic Ocean temperature in deg C (X axis) latitudinal temperature gradient shown from dark blue to dark red triangles. Center is a grey map of the Americas (X axis is longitude). Sites sampled are shown as the same blue to red circles and triangles in their geographical location.

ALT Prince William Sound, Alaska panel with small circular colonies of beige & orange bryozoans, spirorbids & one tiny sea star.

ALT Puget Sound, Washington panel is very similar to Ketchikan, with orange botryllid tunicates, white globular tunicates, tan erect bryozoan colonies, and white barnacles.

ALT San Diego, California panel covered in solitary tunicates with some erect bryozoans around the edges hiding lots of invertebrates underneath.

ALT A grey sanded PVC panel sits vertically on a white surface. The panel is attached to a paving brick with black plastic zip ties and the brick is similarly attached to a beige rope.

ALT The rope, brick, panel, zip tie assemblage is held in the air over a white surface with the sanded side down, the orientation in which it is deployed in the water.

ALT Through clear turquoise water, one sees two fouling panels hanging by their ropes from a dock. A foot dangles off the dock in between them and the undersurface of the dock covered in marine organisms runs along the right side of the photo.

ALT Three fouling panels attached to bricks and rope can be seen hanging in a line underwater from a dock and receding diagonally from vision back and to the right. Somewhat clear dark turquoise water surrounds them.
