The process of ocean acidification can be harmful to the corals at Gray's Reef. Carbon dioxide (CO2) reacts with seawater and carbonate to form bicarbonate which reduces the amount of carbonate available in the seawater. This decrease in carbonate availability can slow growth, weaken skeletons, and make corals more vulnerable to damage or skeletal loss. This poster briefly describes one species of coral at Gray's Reef and how the chemical reactions related to ocean acidification can impact the coral.

Sea Monsters in the Sand
Extensive studies of the tiny animals that occupy Gray's Reef sand bottom (benthic infauna) have revealed the chemical contaminants they carry in their tiny bodies. These tiny sea monsters
are shown in their niches with accompanying text that describe their life.
Invertebrates of the Reef
Over 1000 invertebrates have been identified at Gray's Reef and this colorful suitable-for-framing poster highlights just a fraction in a lovely artistic rendering of the reef and its intriguing boneless inhabitants.
Rivers to Reefs
The Altamaha River Watershed has the most direct influence on Gray's Reef and other ocean habitats off the Georgia coast. Images and text describe the watershed's stages and the components of that influence.
Exploring the Atlantic Seafloor
Ever wonder what it would be like to walk the ocean floor from the USA's southeastern coast to Morocco? Yes, I mean Africa! Images from a satellite, a transect and of several different ocean habitats with accompany text let you explore without even getting wet! So go ahead, take that walk.
This colorful poster does beautiful duty as a game board. Students learn about sea turtles common to the Atlantic and when playing the game they encounter all the challenges a
hatchling faces on its journey to becoming an adult.
Gray's Reef Poster
Gray's Reef National Marine Sanctuary boundaries encompass the best examples of a calcitic sandstone reef. Locals refer to this type of habitat as a hard-ground, live-bottom. However you prefer to call it, Gray's Reef is a very healthy subtropical reef. A location map and beautiful images of the reef are featured.
