Marine biology is a vast and fascinating subject; oceans cover 71% of the Earth’s surface, and 80% has yet to be explored.
Some of the most crucial and cutting-edge research in environmental science takes place in the field of marine biology, and the discipline has long been at the forefront of climate change research.
It should come as no surprise that some of the best undergraduate and graduate programs for marine biology are located in California.
The coast of the Pacific Ocean is an ideal place to study marine life, and some of the world’s top marine science research centers are located at California universities.
Marine biology may be housed under the umbrella of a school’s biology or environmental science department, and depending on the institution, it may be called marine science, environmental and ocean science, aquatic biology, or something else.
So, students seeking a marine biology program should not restrict themselves to that search term; instead, they should investigate whether a particular school has a program devoted to studying the ocean, regardless of what it is called.
To complete a marine biology major, students will usually have to complete a core set of courses in the biological sciences and may be required to take courses in chemistry, math, statistics, and physics.
Field research is also a typical component of marine science programs, and students will have the opportunity to study some forms of marine life in their natural habitats.
Many research universities in the field of marine biology collaborate with one another and partner with organizations and agencies where students can get hands-on experience and participate in vital research on marine life and environments and climate change, such as the Hubbs Seaworld Research Institute, the National Oceanic and Atmospheric Administration (NOAA), the Southern California Marine Institute, and more.
Here is a list of colleges in California with a marine biology program.
