The geology of Alabama is marked by abundant geologic resources and a variety of geologic structures from folded mountains in the north to sandy beaches along the Gulf of Mexico coast. Alabama spans three continental geologic provinces as defined by the United States Geological Survey , the Atlantic Plain, Appalachian Highlands, and Interior ...
In the northern part of this plateau, west of Jackson county, there are about 1,000 square miles (2,600 km 2) of level highlands from 700 to 800 feet (210 to 240 m) above sea level. South of these highlands, occupying a narrow strip on each side of the Tennessee River , is a country of gentle rolling lowlands varying in elevation from 500 to ...
Chlorophyll maps from 2002 to 2024, provided by NASA, show milligrams of chlorophyll per cubic meter of seawater each month. [45] Places where chlorophyll amounts are very low, indicating very low numbers of phytoplankton, are blue. Places where chlorophyll concentrations are high, meaning many phytoplankton were growing, are yellow.
Higher chlorophyll concentrations generally indicate areas of enhanced primary production, and conversely lower chlorophyll levels indicate low primary production. This co-occurrence of low chlorophyll and high macronutrient availability is why these regions are deemed "high-nutrient, low-chlorophyll."
Low-nutrient, low-chlorophyll (LNLC) regions are aquatic zones that are low in nutrients (such as nitrogen, phosphorus, or iron) and consequently have low rate of primary production, as indicated by low chlorophyll concentrations. These regions can be described as oligotrophic, and about 75% of the world's oceans encompass LNLC regions.
