- How does decreasing salinity affect blackwater rivers?
- In A blackwater river from sea to source: The White Oak River transect, page 2
- All rivers that reach the sea have ocean water at their seaward ends, and freshwater at their sources. A trip up a river takes you along a gradient of salt concentration from near 3.5 percent (the average salinity, or salt content, of seawater) to zero. There...

- White Oak River estuary
- In A blackwater river from sea to source: The White Oak River transect, page 8
- Figure 6 is a view of the high salinity, open water area of the White Oak River estuary about 4 miles inland of the mouth. Salt marsh still occurs on the estuary floor, but it is clearly much less extensive than closer to the ocean and its sources of sediment....

- Hurricanes and coastal development
- In Hurricanes on sandy shorelines: Lessons for development, page 1
- North Carolina's location at the eastern end of the southeastern U.S. coastline makes it a frequent site of hurricane landfalls. These landfalls are a regular feature of the state's climate, as they are a natural outcome of the its proximity to the most frequent...

- How do hurricanes form?
- In Hurricanes on sandy shorelines: Lessons for development, page 2
- Hurricanes begin when areas of low atmospheric pressure move off Africa and into the Atlantic, where they grow and intensify in the moisture-laden air above the warm tropical ocean. Air moves toward these atmospheric lows from all directions and curves to...

- How do hurricanes cause damage to coastal infrastructure?
- In Hurricanes on sandy shorelines: Lessons for development, page 2.1
- A fully formed hurricane carries three major threats to coastal development: low atmospheric pressure, high surface winds, and heavy rainfall. These threats are realized in different ways. Low central pressure becomes a threat when...

- Colonial restrictions on pottery
- In Clays of the Piedmont: Origins, recovery, and use, page 8
- European colonists recognized clay as an important resource in developing their agricultural economy. Surprisingly, the king's governors restricted the manufacture of pottery because the British economic model for the empire (called mercantilism)...

- You (yes, you!) are making a difference: The power of a single phrase
- In The First Year, page 2.5
- A teacher's goal is to reach every student, but while you are working on big issues and ideals, take advantage of the small moments that your position affords you.
- By Kristi Johnson Smith.
- Welcome back!
- In The First Year, page 3.1
- Many of my friends are in professions other than teaching, and one January evening I listened as one of those friends described how much he loved the first day back at work after the winter holidays. He detailed that day, depicting a slow morning devoted to...

- Who's holding the pencil? And did anybody learn?
- In The First Year, page 3.4
- Demonstrations can be useful, but be aware of what students are doing and thinking while you're holding the pencil.

- Small and large sand volume barrier islands
- In Small sand volume barrier islands: Environmental processes and development risks, page 1
- Barrier islands are the dominant geographic feature of sandy coastlines, but recurring storm damage on some demonstrates that different barrier islands present very different levels of risk to residential development. One of the best indicators of development...

- Small and large sand volume islands
- In Large sand volume barrier islands: Environmental processes and development risks, page 1
- This field trip follows another in this series, Small Sand Volume Islands. Readers should plan to take these trips sequentially, to compare the two types of islands. The thesis of both trips is that the volume of sand that comprises...

- Early-stage forest
- In Large sand volume barrier islands: Environmental processes and development risks, page 8
- Figure 7 shows an earlier and more problematic stage of maritime forest development on Bear Island. Here we see a live oak on which all the seaward branches have been stunted by salt-laden wind off the ocean, leaving only those on the lee side of the trunk...

- Fort Macon State Park
- In Large sand volume barrier islands: Environmental processes and development risks, page 13
- Figure 12 shows the dunefield at Fort Macon State Park on Bogue Banks. This is a typical setting for maritime shrub and forest development. Note the large and well vegetated dunes. These raised mounds of sand are called hummocky dunes — a...

- Mentor's guide
- My first words to any veterans, mentors and administrators reading this section should be “thank you.” The support and counsel you offer new teachers is invaluable. It is my hope that The First Year will assist you...

- The northern Outer Banks
- In Natural and human impacts on the northern Outer Banks, page 1
- The United States is currently experiencing a population boom along its eastern coast, and the development of beaches and coastal areas is taking place at an alarming rate. As humans invade the coastal zone, more and more reports are heard of erosion and property...

- Dune formation
- In Natural and human impacts on the northern Outer Banks, page 4
- The migration of dunes in response to the prevailing winds is an important process on the Outer Banks. Nags Head Woods is flanked on three sides by large dune fields. To the north of the woods is the Run Hill dune field. Run Hill Dune is an unusually large,...

- The unpainted aristocracy of Nags Head
- In Natural and human impacts on the northern Outer Banks, page 10
- In northern Nags Head some seaside homes have survived the frequent storms of the Outer Banks. Located near the intersection of Virginia Dare Trail (NC 12) and East Soundside Drive, these “unpainted aristocracy” homes are the oldest summer cottages...

- Cape Hatteras Lighthouse
- In Natural and human impacts on the northern Outer Banks, page 19
- No structure better symbolizes the human struggle to cope with natural processes of the Outer Banks than the Cape Hatteras Lighthouse. The first Cape Hatteras lighthouse was built in 1802, more than 3,000 feet from the coeval shoreline. The base of that first...

- Forests and fires
- In Forests and fires: The longleaf pine savanna, page 1
- Americans of different eras have viewed forest fires very differently. Most modern Americans view them as natural disasters. They base this opinion on widely publicized devastating fires that have swept through the brushland areas near Los Angeles and Yellowstone...

- Three-year burns
- In Forests and fires: The longleaf pine savanna, page 4
- Figure 3 shows a longleaf savanna that is being burned at three year intervals. Note the almost complete absence of broadleaf trees on the forest floor, and the pines of many different sizes. The different sized pines indicate that pine regeneration has occurred...
