Aquatic Remote Sensing - Example spectra of water, water with algae, and water with sediment

Example spectra of water, water with algae, and water with sediment. The x-axis is wavelengths of light. For remote sensing of water, we are only interested in the visible range (400 nm – 700 nm) and a little bit of the ultra violet and infrared. The y-axis is the amount of light in each wavelength.

Two glasses of water, the one on the left has dissolved organics and particulate matter in it making it brown and cloudy. The glass on the right is clear and clean and colorless. This illustrates the main concept of aquatic remote sensing: water color changes based on what’s in it and we can link those color differences to differences in composition.

Examples of spectral resolution. High resolution sensors image many bands (i.e., colors) and lower resolution sensors image fewer bands. Higher spectral resolution lets us view more of the spectrum, but has cost, data storage, and band sensitivity trade-offs.

Low versus high radiometric resolution. Low resolution is low data storage, meaning only a few shades can be seen (as in the left image), high resolution is more data storage and means more shades can be recorded (right image).

RUSH is a tool for rapid repeat high resolution coastal vegetation maps to improve forecasting of hurricane impacts and coastal resilience. Vegetation cover in coastal settings significantly controls flooding, erosion, and barrier island breaching during extreme storms by reducing wave energy.

We have experienced the placement of rocks on hillsides in eroded areas. The rock dams capture silt and water. A great many dams placed close together in all drainages capture so much water that the hills become sponges.

Lucinda Cole and I retired to the Pitchfork Ranch in southwest New Mexico two decades ago. We’ve overseen 17 government grants to install grade-control structures in 31 side-drainages and the ranches’ 9-mile reach of the 48-mile-long Burro Ciénaga riparian watercourse, 1.5-miles perennial ciénaga.

We live in the Anthropocene. The entire surface of the earth has been impacted by human activity and our land management decisions. In this context, most of the grasslands in arid and semiarid regions are experiencing severe and continuing degradation.

The use of simple erosion control structures, one-rock-dams, rock sills, trincheras, etc have gained great popularity in recent years.  Ease of construction, relative cost and effectiveness are driving increased and widespread use.
