Paramo meadows near Ambato, Ecuador Each region has different factors that affect its climate. The Costa is influenced primarily by proximity to warm or cool ocean currents. By contrast, climate in the Sierra varies more as a function of altitude.
It originates in the depths of the western Pacific Ocean and flows eastward. Together, they slam into the islands, pushing deep cool water to the surface. The deep water has an abundance of accumulated nutrients.
This enormous submarine river current is miles wide, miles long and is times the volume of the Mississippi River. The surface currents of the Pacific Ocean Galapagos Penguin Photograph from Creative Commons by Hanumann The Galapagos Penguins also rely on this ocean current as it brings nutrient-rich fish on which the penguins feed.
The very cold Cromwell Current just 13 degrees Celsius at its core lies feet underneath the surface current and is like a river flowing in the opposite direction. Because it is so high in nutrients and oxygen, the Cromwell Current supports a wide array of marine life.
It is unusual for the Cromwell current to appear in the eastern Galapagos Islands. For the most part, it surfaces near the western islands of Fernandina and Isabela. Then, upon encountering the submarine Galapagos platform it dissipates toward the center of the archipelago.
The Cromwell Current has a dramatic impact on the marine environment throughout the Galapagos Islands. Recently a blogger wrote about his diving experiencing around Isabela Island in the Cromwell Current, where the water temperature is about 58 degrees F 16C. He identified varied and fascinating marine life that might be encountered in this nutrient rich environment: After one of our dives we did a panga ride along the cliff where we spied penguins, flightless cormorants, marine iguanas relaxing, hunting and swimming, sea lions, pelicans, and resident blue footed boobies.
Panama Current The Panama Current is a warm water current that predominates from about November the beginning of what we call the "wet" season until May. The water temperature rises, the skies clear with the exception of occasional rain showers.
The water during the period of the Panama Current is actually clearer because there are fewer nutrients concentrated in it. The marine life is very rich during this period as well. The warm water brings loads of schools of fish as well as sharks and rays.
Instead of allowing the Humboldt Current, so rich in nutrients, to come in to feed and nourish the aquatic life and the animals and birds that depend on that marine life for survival, the warm waters stagnate around the Galapagos archipelago.
The aquatic life typical to the Galapagos Islands is unable to survive in the absence of cool water rich with nutrients. So, the fish leave the archipelago in search of cooler waters in which to thrive.
The result can be devastation as the marine and animal life that depend on the schools of fish is left without a food source. Iguanas Shrink in both weight and height without nutrition Photograph from Sciencewithoutborders.
And when the feed cycle is broken, so is the breeding cycle. The long-term impact on the fish, birds and marine animals that depend on those fish for survival is challenged. Tortoise species have died because of El Nino. Land iguanas shrink in both height and weight when forced to live without sufficient nutrition during a period like El Nino.
Read more about this occurrence in my Iguana blog post. From a satellite, it photographed the amounts of chlorophyll in the water during and after El Nino.
Blue represents low concentrations, while yellow, orange and red indicate high concentrations. The images from graphically show that the unique Galapagos ecosystem was severely affected and many species, including sea lions, seabirds, and barracudas, suffered a very high mortality level.
However, during the second week of May,the ocean temperatures plummeted 10 degrees in one day, and the ocean productivity exploded with large phytoplankton blooms. Rapidly, many species recovered and the land species started to reproduce.
There are photographs of the devastation that El Nino had on marine lifeincluding sea lions and iguanas. During a period of El Nino the Galapagos National Park Service is diligent in following and studying all the animal, bird and marine life and providing human support to forestall harm to any species.Taxidermist Erling Hansen, zoologist Alf Wollebæk and author John W.

That hunting orgy almost . Everyone knows the privileged place of the Galapagos Islands in Natural History, but not as many know that the geology of the islands is as fascinating as the wildlife!
The story of how the Galapagos Islands were born is an important part of understanding them today. Geography (from Greek γεωγραφία, geographia, lit.
“earth description”) is a field of science dedicated to the study of the lands, the features, the inhabitants, and the phenomena of the Earth. The Galapagos Islands are a territory of Ecuador. Its flag is a tricolor combination of green, white and blue.
It is believed that the flag was first hoisted for the San Christobal Republic in , on the island of San Christobal, long before the islands become a province in , and subsequently a .
