Islands Marías and Teacapan Estuary, Mexico

21.6N 106.5W

February 28th, 2012 Category: Lakes, Rivers

Mexico - January 4th, 2012

Visible on the left side of this image are the Islas Marías, an archipelago of four islands that belong to Mexico. They are located in the Pacific Ocean, some 100 km (62 mi) off the coast of the state of Nayarit. They are part of the municipality (municipio) of San Blas, Nayarit. In 2010 the archipelago was designated Biosphere reserve by the UNESCO.

Visible on the mainland opposite the islands (the green area along the coast to the northeast of the archipelago) is the Teacapan Estuary. This long outlet drains two large coastal lagoons, Agua Grande Lagoon in Sinaloa on its northern end and Agua Brava Lagoon in Nayarit at its southern end, into the Pacific Ocean at its mouth, the Boca Teacapan. The estuary forms part of the border between the Escuinapa Municipality, Sinaloa, and the Tecuala Municipality of Nayarit. The Teacapan Estuary is also fed by the Acaponeta River in its southern arm, and the Cañas River in the northern arm

Vegetation Index of Pacific Coast of Mexico and Islas Marías

Mexico - January 4th, 2012

This FAPAR image shows the vegetation index of the Pacific Coast of Mexico, in the states of Sinaloa, Nayarit and Jalisco (following the coastline from the upper left to the bottom right). The index is highest along the coastal plain, where green false-coloring indicates good levels of photosynthetic activity.

The index becomes progressively lower (yellow) as one moves further inland. A few patches of high activity (rusty red) can be observed in a marshy area near the coast, parallel to the Islas Marías (“Mary Islands”), an archipelago of four islands that belong to Mexico. They are located in the Pacific Ocean, some 100 km off the coast of the state of Nayarit and were designated a Biosphere reserve by the UNESCO. Here, they show good photosynthetic activity.

Track of 10E

At 8:00 PM PDT (0300 UTC) the center of Post-tropical Cyclone Jova was located near latitude 21.7 north, longitude 104.2 west.

The post-tropical cyclone is moving toward the northeast near 5 mph (7 km/h) and a slow northeastward motion is expected until dissipation.

Maximum sustained winds have decreased to near 30 mph (45 km/h) with higher gusts. Continued weakening is forecast, and the system should dissipate in a day or less. The estimated minimum central pressure is 1008 mb (29.77 inches).

Hazards affecting land consist mainly in rainfall; the remnant of Jova is expected to produce total rainfall accumulations of 2 to 4 inches over the states of Michoacan, Colima, Jalisco and Nayarit through Thursday.

Vegetation Index of Nayarit and Central Mexico

Mexico - January 25th, 2010

This FAPAR portrays central Mexico, between the Pacific Ocean (west) and the Gulf of Mexico (east). While much of the inland area is desert and thus appears white to yellow, indicating very low photosynthetic activity, some more productive areas can be observed in green and dark red along the shoreline.

The most productive of these appears dark green to red, indicating high photosynthetic activity, in the lower left quadrant. This zone is in the state of Nayarit, on the central west coast, bordering the Pacific Ocean. Its terrain is broken up by the western ends of the Sierra Madre Occidental mountains. Nayarit has hundreds of miles of rain forest in the sierra. Unfortunately most of the rain forest has been exploited, especially around the region of Santa Maria Del Oro.

Lagoons and Aguamilpa Dam Reservoir, Mexico

Mexico - March 19th, 2009

Various lagoons filled with dark brown and green water can be noted along the western coast of Mexico. The largest lagoon, just below the center, is the Agua Brava Lagoon.

Moving up the coast, the dark curvy line of a river connects the Agua Grande Lagoon to the Pacific Ocean. Continuing northwestward, the El Caimanero Lagoon can be seen near the edge of the image.

Further inland, east of the Agua Brava Lagoon, is a large reservoir whose waters appear green. This reservoir, which covers a large part of the territory of the municipality of El Nayar in Nayarit, was created by the Aguamilpa Dam on the Río Grande de Santiago, built in 1997.

The river descends from the reservoir to the coastal lowlands, passing by Santiago Ixcuintla and empties into the Pacific Ocean 16 km northwest of San Blas, in Nayarit. A small amount of sediments can be seen flowing forth from its mouth.
