| What's harvested from CB | Blue crabs, oysters, stripped bass |
| Goods and services provided by CB | High NPP |
| How long is the CB | 200 miles long |
| Salinity of CB | Freshwater to 24 ppt, salinity increases when getting closer to ocean |
| What is brackish water | Not frest, not salt |
| Where do you find impacts of surge | Tidal area |
| What is SAV | Submerged aquatic vegetation |

| Major threats to CB | Over harvesting or resources, watershed development, pollutions, nutrients and sediments |
| Study of interactions between living and non living | Ecology |
| What does it mean for the CB to be a ecological zombie | Not quite dead certainly not alive, but a grottoes shadow of what it use to be |
| Goods , services of oysters in the CB | Filter, provide habitat, and food, pump large bodies of water. |

| How much outflow occurs from the Great Lakes | 1% |
| How is retention times calculated | Volume divided by average rate of inflow or outflow. |
| Can more than one watershed be found in one state | Yes, because of the particular topography of the surrounding area. |
