Zane Grey Creek with Alyssa Bates and Arin Hurd

Zane Grey Creek

This location had the most turbidity (~10 ft) compared to the other sites we visited. The high turbidity could have been associated with the fine sediments that composed the habitat. This turbidity also could have been attributed to the abundance of microbial organisms throughout the water column. With the abundance of microbial organisms, this allowed filter and suspension feeders such as Cnidarians and Porifera.

Red Mangroves were the prominent vegetation around this area. The mangroves are an important feature for this area because they protect the shorelines from erosion, they provide a sanctuary for smaller fish, and they help to filter out the water.

The depth of the water was shallow near the mangroves and dramatically dropped off approximately five to ten feet away from the mangroves. Since the turbidity in this area was high, seeing the bottom of the creek at the drop off was difficult.
