The Chesapeake Bay is a large coastal-plain estuary that has experienced considerable anthropogenic changeover the past century. At the regional scale, land-use change has doubled the nutrient input from rivers and led to an increase in riverine carbon and alkalinity. The bay has also experienced global changes, including the rise of atmospheric temperature and CO2. Here we seek to understand the relative impact of these changes on the inorganic carbon balance of the bay between the early 1900s and the early 2000s. We use a linked land–estuarine–ocean modeling system that includes both inorganic and organic carbon and nitrogen cycling. Sensitivity …

Sediment classification and grain size can affect the types of organisms that live in the sediment. Some organisms prefer sandier sediment, while others love the fine-grained mud.
In this activity, students will classify sediment samples by grain size and plot their findings on a ternary plot. The students will then further investigate which benthic organisms live in the different sediments and which may be more resilient to a change in sediment classification.
