Meet a few of our explorers focusing on all things ocean! Check out our archive of Explorer Classroom events to meet even more. 1. Meet Sylvia Earle “Called “Her Deepness” by the New Yorker and the New York Times, “Living Legend” by the Library of Congress, and the first “Hero for the Planet,” Sylvia is an oceanographer, explorer, author, and lecturer with experience as a … Continue reading Five Female Ocean Explorers
Shannon L. Switzer Swanson is an award-winning photographer, published writer, and National Geographic Young Explorer whose work focuses on ocean conservation. There are many definitions of a “hero.” Each of us has our own personal opinion of the qualities a hero must possess and the people we personally consider to be heroes. I don’t know about you, but the idea of a hero as a … Continue reading How to be an Ocean Hero
The ocean covers 70% of the surface of Earth. It is a vital natural resource that produces food and oxygen, and has been key to trade and exploration for thousands of years. Despite this, our ocean is being damaged by overfishing, pollution, invasive species, acidification, and sea temperature rise. Ocean conservation will be one of the future generation’s defining missions. Photography courtesy of George F. … Continue reading National Geographic Encounter: Ocean Odyssey Special Collection: Treasure Trove of Ocean-Themed Classroom Material
This blog is written by outdoors family blogger Laure Latham, as a part of the Geography Awareness blog-a-thon. When I started thinking about GeoWeek’s blog-a-thon, I considered the meaning of geography. In simple words, geography is the science of places and the relationships between people and their environments. It’s the land, the water, the people and everything else around. Based on that definition, I needed to know why geography … Continue reading Why Children Need To Care About the Ocean
Today we welcome Dr.
Enric Sala, a National Geographic Emerging Explorer,* whose research in marine
ecology has shed new light on coral reefs systems. Before coming to National Geographic, Dr.
Sala was a researcher at Spain’s National Council for Scientific Research and a professor at Scripps Institution
of Oceanography. When he left academia
to concentrate on his research, Dr. Sala employed a rare, optimistic
methodology: He did not study environmental degradation like most scientists,
but concentrated on what pristine ecosystems could teach us. This optimism led him to study the coral
reefs around the Line Islands in the Pacific Ocean. The islands host different numbers of human
inhabitants, and show how population change directly impacts the surrounding reefs. His research was ground-breaking in its
findings and holistic in its approach.
Dr. Sala is now
working with National Geographic to create a platform for different non-governmental
organizations (NGOs) and conservation organizations to discuss environmental innovations,
while continuing his research. Many thanks to Enric Sala for helping us
celebrate environments during Geography Awareness Week!
*In the days since publishing this post
we learned that Enric has newly been named a National Geographic
Fellow. Congratulations, Enric!
1) What inspired you to become a marine ecologist?
I was lucky that two things happened to me when I was a kid
in Spain. First, Jacques Cousteau’s movies were at their prime and shown on TV; I watched
all of them and dreamt about being a diver in the Calypso and explore the
oceans. Second, I lived near the coast and was able to swim and snorkel during
most of my childhood, which gave me a sense of appreciation and love for marine
life first hand, in a way that no book or TV program can.
2) Why is it important to study our oceans?
The oceans are essential to human life and well-being. They
produce more than half of the oxygen that we breathe, regulate the climate, and
provide us with food. We need to understand how to not damage the machine that
3) Please tell us a
little about your scientific findings, specifically from your study in the Line
Islands of the Pacific Ocean.
In 2005 and 2007 we conducted an expedition to Kingman
Reef, in the Line Islands, Central Pacific.
Kingman is a pristine coral reef, a time machine that transported us back
hundreds of years ago. What we found surprised us, because we did not know that
on a pristine, healthy coral atoll, top predators account for 85% of the fish
biomass. This is similar to the Serengeti with five lions per wildebeest! It is
the landscape of fear, where predators roam free and the prey are hiding. We
also found that an intact food web is more resilient to the short term effects
of global warming; that is, on a healthy reef, corals may bleach because of a
warming event, but they can recover relatively quickly.
4) Please describe your theory of doing research. Why do you study the entire ecosystem, from
algae to sharks, as opposed to one particular component like other scientists?
Ecosystems are composed of many thousands of species
interacting together. We cannot understand how these ecosystems work without
looking at as many of their components as possible. Imagine trying to
understand how Picasso painting by looking at just one color at a time…
Science needs both specialists and generalists, but fortunately, there is an
increasing number of scientists studying ecosystems.
