1.How has the ratio of floating algae to sea floor algae changed over time? Whatdoes this indicate about today’s level of nutrient pollution as opposed to thenutrient levels 300 years ago?
2.Why did the arrival of European settlers cause the ratio of floating to sea flooralgae to begin to increase (at around 1750), even though they were not yet
harvesting oysters on a large scale? What were the new settlers doing on landthat might have been affecting the algae levels in the water?
3.The ratio of floating algae to sea floor algae held steady for a very long time ataround three and then suddenly increased towards eight starting after 1930. Whathappened to the oyster catch over the same time period?
4.How might the decline of oysters lead to the sudden increase in the ratio offloating algae to sea floor algae levels?
5.Why are so few oysters being caught today as compared to the end of the1800s?

Creating Artificial Habitat to Restore OystersOyster larvae spend their first few weeksof life as floating zooplankton but theyneed a hard substance to attach to inorder to develop into adults.Dredging ofthe sea floor by the oyster fishery hasremoved many natural oyster reefs andoyster larvae cannot find an appropriatelocation to settle. Scientists can createartificial oyster reefs from concrete orfrom old oyster shells to help youngoysters get established.Larvae settle onthe surface of the artificial reef and canestablish new oyster colonies.6.How would you use oysters to solve the problem of algae overgrowth and alsohelp the oyster industry? What changes or trends in species abundance wouldyou measure to determine how the bay is responding to your restoration efforts?
