Bays Along Gulf Coast of Texas, USA and Tamaulipas, Mexico

Mexico – November 7th, 2012

This image shows a portion of the Gulf Coast, made of many inlets, bays, and lagoons, by the Texas, USA – Tamaulipas, Mexico border. The western portions of the Gulf Coast are made up of many barrier islands and peninsulas, including the 130 miles (210 km) Padre Island and Galveston Island located in the U.S. State of Texas. These landforms protect numerous bays and inlets providing as a barrier to oncoming waves. Here, those bays appear various shades of green and light blue due to the presence of sediments and phytoplankton.

Sediments in Gulf of Mexico and Peaks of Sierra Madre Oriental, USA and Mexico

USA - September 26th, 2011

Sediments line the Gulf of Mexico by the coast of Texas, USA. Once one moves beyond the border, into the Mexican state of Tamaulipas, fewer sediments are visible along the shoreline.

While the land in Texas appears mostly flat, once one moves into Mexico the crests of the Sierra Madre Oriental can be observed. Heavily vegetated, they appear darker green and brown than the surrounding area.

Mexico - December 6th, 2010

This APM image shows parts of the states of Tamaulipas and Nuevo León in eastern Mexico. The terrain changes from flat, to hilly as one moves southwards, with a ridge of mountains visible near the bottom.

This ridge is known as Cerro el Hongo, or the “Mushroom Peak”. Its maximum elevation is about 1800 meters (5905 feet). The ridge is located in the state of Tamaulipas.

Laguna Madre, Gulf of Mexico

Laguna Madre, Gulf of Mexico - March 19th, 2009

The Laguna Madre is the name of two long, shallow bays along the western coast of the Gulf of Mexico in the United States and Mexico; the two being separated by the outlet of the Rio Grande.

Meaning “mother lagoon” in Spanish, the Laguna Madre proper is 130 miles (209 km) long, the length of Padre Island. Its biological corridor, though, extends well into Mexico, to the mouth of the Río Soto la Marina in the state of Tamaulipas.

In the United States, the section visible here, Laguna Madre is separated from the Gulf of Mexico on the east by Padre Island, and bounded on the west by mainland Texas, and extends from Corpus Christi in the north to Port Isabel in the south.

In Mexico, Laguna Madre is separated from the Gulf of Mexico on the east by a number of barrier islands, including Barra Los Americanos, Barra Jesús María, and Barra Soto la Marina. It is bounded on the west by mainland Tamaulipas.

The Laguna Madre is very shallow, with an average depth of only 0.9 m. It is connected to the ocean by only two narrow inlets, so the tidal range – which is already minor in this part of the Gulf of Mexico – is negligible.

Oceanographically, the Laguna Madre is considered a hypersaline lagoon; this indicates that it is usually much saltier than the ocean, due to being nearly landlocked in a semiarid environment, and is one of only six hypersaline lagoons in the world. The Laguna Madre has been experiencing a persistent algal bloom (including drift algae) that may be partially caused by its hypersaline conditions, which favor algal growth.

Atmospheric effects are much more important than tides in its circulation; its weak currents generally follow the prevailing winds, and these winds can influence the water level by as much as a meter. Some such currents are visible to the South, their movements made visible by green algae.
