What motivated early ocean explorers
By: Retha Boswell
From 1872 to 1876 the HMS Challenger explored all of the world’s oceans, with the exception of the Arctic. The Challenger Expedition is considered the turning point for modern oceanography because it was a large-scale, government-funded project with the sole purpose of ocean research...
What has drilling into the sea floor contributed to ocean science?
By: Retha Boswell
Ocean drilling or the probing of the sea floor is an important method used by oceanographers to learn about seas and sea life. In the early years of ocean science, the scientists dredged and collected sediment samples from the ocean floor because they did not...
How the change in sea level impacts animal life
By: Retha Boswell
Rising sea levels are a reality. The rate of rise over the past twenty years is double what it was during the preceding eighty years. This will impact coastal cities, and small islands will be at risk of completely vanishing if the trend continues. What...

What actually is sea level? Sea level or ‘mean sea level’ as it is known, is the average height of the ocean’s surface between high and low tide. Changes in tides and wave conditions over time are averaged out to determine a &lsquo...
Instruments commonly used in oceanography
By: Kimberly Napier
The study of the Earth's oceans and its boundaries is called oceanography. The oceans, which overs over 70 percent of the surface of the world, are interconnected. Humans rely on the oceans for food, as a source of weather and their climates. The oceans are...
How the change in sea level impacts animal life
By: Kimberly Napier
The water temperatures around the world are rising, as this occurs, the water level also rises. As the each drop of water become warmer they expand. This expansion of each of the drops in the ocean cause the sea levels to rise. At the same...
What has drilling into the sea floor contributed to ocean science?
By: Kimberly Napier
Since the first ocean exploration of the Challenger, ocean exploration has been driven by the desire to know what the ocean floor can tell the world. One way to do this exploration is through drilling into the ocean floor. Drilling is done by sending a...
