The scientific reasons behind Earth's seasons
By: Jose Juan Gutierrez
The Earth's seasons are the result of the Earth's rotation around the Sun and the tilt of its axis relative to the ecliptic. The seasons mark the time of year when the Earth experiences weather and ecological changes. The seasons in different regions in the...
How the Challenger Expedition shaped the science of oceanography
By: Retha Boswell
The turning point of modern oceanography occurred between 1872 and 1876 when the HMS Challenger set sail for the sole purpose of exploring the world’s oceans. The Challenger Expedition sought to collect data on ocean temperatures, water chemistry, currents, marine life, and the seafloor...
How the Challenger Expedition shaped the science of oceanography
By: Jose Juan Gutierrez
The Challenger expedition was one of the first scientific expeditions intended to gather data about the ocean's unexplored features. During the expedition which lasted from 1872-1876, the scientific crew gathered data on the temperature, water chemistry, currents, marine organisms and ocean floor deposits. The Challenger...
How the Challenger Expedition shaped the science of oceanography
By: Kimberly Napier
Oceanography is the study of the Earth's oceans and the boundaries. This waterway, which is interconnected cover over 70 percent of the earth's surface. Humans have always had a close tie to the oceans. We use it for food and a way to predict weather...
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...

Erosion occurs when elements, such as water flow or wind remove small particles of soil or rock from the surface of the Earth. These small particles are carried away and deposited in another location, leaving a degraded land, affecting agricultural production, due to the loss...
What motivated early ocean explorers
By: Jose Juan Gutierrez
Ocean exploration has been one of human being's occupations since the invention of boats and ocean vessels. Even though, people have sailed the world's oceans for thousands of years, most ocean exploration has been done at the surface level. It was not until the mid...

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...
