Have you ever wondered if plankton are really that important to us? Before this lab, I never even thought about plankton, or how they even contribute to us. Phytoplankton are able to convert carbon dioxide into carbohydrates and oxygen used for life (through photosynthesis), and they account for about 95% of the ocean’s primary productivity, while providing about half on Earth. Phytoplankton is a primary food source to zooplankton and the rest of food web in the ocean. The marine food web is really
Marine Careers Marine biology is the field of knowledge relating to any kind of marine organism, dolphins, whales, sharks, seals, plankton, etc. But what is a marine biologist? Well to a lot of people, the first thing they think of is Shamu and training dolphins but to others it means managing a marine wildlife sanctuary. There are multiple answers to this question and none of them are wrong answers, but to me a marine biologist is someone who has anything to do with the marine life, whether it be
There are many human activities and industries that causes marine pollution within our oceans. There is not only one source that causes marine pollution, there several other factors involved as well. One source of marine pollution is NOx and SOx, these are chemicals that are found in ship emissions that gets released into the environment through smoke; NOx and SOx are known to be very harmful to marine life (Raunek). Because of the fact that there are many types of ships out there in the ocean, the
Biological oceanography studies marine species as well, but in the context of oceanography, whereas marine biology studies the ocean along with different salt-water environments. Although there is a difference between these two terms they are usually easily interchangeable. Marine biology requires many different fields of science, including astronomy, biological oceanography, cellular biology, chemistry, ecology, geology, meteorology, molecular biology, physical oceanography and zoology
Oceanography H. P. Lovecraft once said “Ocean is more ancient than the mountains, and freighted with the memories and the dreams of Time.” (Lovecraft, n.d., Ocean Quotes). Extracting information from times past is what some are researching today. The oceans are vast and mysterious but with the advent of new technology many unmanned submersibles are being built and used to find out more on the mysteries of the ocean. A brief introduction to what oceanography encompasses along with a little history
“Oceans of pollution”, written by Dahr Jamail. The author intent is to inform the reader of United States (US) in general population. This article provide the information on the plastic pollution that has increase which negatively impact on the ocean biological system and creation of “dead zone” by the humans influence. The author suggest that although the negative impacts of the plastic waste on the ocean is not well known by the people, it is up to the government agency, such as US Environmental Protection
In some instances, a speaker’s reputation immediately establishes ethos. They are expertise, knowledge or experience. This strategy gives the audiences a reason for listening. For example, Dr Debora Iglesias-Rodriguez, a biological oceanographer, with the National Oceanography Centre at Britain’s University of Southampton said that the food chain are affecting fish fertility rates and this affects food security and coastal population. The author mentions that the pollution is having a huge impact
Have you ever tripped on a discarded and worn-out Happy Meal toy while walking along the beach shore? Has it ever dawned on you that this piece of garbage can be a habitat for different microbes that have created their own community? For the past 60 years, humans have been unconsciously creating a new ecosystem in the oceans. This ecosystem is made up of different things—from toys and shoes to orange juice containers and toothpaste tubes. Labeled as the plastisphere, scientists are now concerned
huge water mass in front of me? What were the wonders hidden in the ocean? As I grew, I decided I need to find the answer to those questions and studied Marine Sciences at college. While advancing in my degree, which I was projecting in physical oceanography, I realized that it was not only a matter of physics but ultimately, a series of feedbacks between other natural systems in the Earth and even out in space. Thus, I felt the need to satisfy my curiosity and start a degree in Environmental Science
"By and large, reefs have collapsed catastrophically just in the three decades that I've been studying them," said Nancy Knowlton, a marine biology professor at the Scripps Institution of Oceanography in La Jolla, California. Knowlton, who is also a member of National Geographic Society Committee for Research and Exploration, notes that corals live precariously close to their thermal limits. As a result, even the most isolated reefs are vulnerable

cause massive nutrient loading in an ecosystem, but by reducing the amount of washing you do within the week, or using earth friendly washing detergents and fertilizers, this problem can be reduced. Marine Pollution: Causes Aquatic Biodiversity Biological diversity is the variability among living organisms from many different sources including marine and aquatic ecosystems, and the diversity within species and of ecosystems. (Gray 1996) Some of the major components of marine biodiversity include
J. Anderson Stephanie Branscum Dr. Sylvia 1. Yes, Dr. Sylvia Earle has the authority to speak on this subject because she is the first woman to serve as NOAA’s Chief Scientist, ocean explorer, and marine biologist, and has other qualification that makes her reputable. According to Harte Research Institute, “Dr. Sylvia Earle is a marine biologist, ocean explorer, author, lecturer, first woman to serve as NOAA's Chief Scientist, and now Explorer-in-Residence at the National Geographic Society. She
The Bathypelagic Zone and its Food Pyramid The Mysterious Deep The ocean covers 71% of the Earth’s surface, yet 95% of the deep ocean has not been explored.(NOAA, 2015) With the current technology it is still difficult for humans to investigate in the deep due to the intolerable pressure and the enormous creatures such as the giant squid, and others that are still unknown. However, using current technology, more and more information has been obtained. The veil of the deep ocean is slowly being
For years corporations have been depleting the oceans of its wildlife for our benefit. However, one thing these corporations tend to not mention is the bycatch they encounter when catching fish for the purpose of consumption. The definition of bycatch “is the unintended capture of nontarget animals…”(Crowder and Murawski pg.1). Bycatch takes a negative toll on our ocean ecosystem that cannot be reversed. Why does bycatch occur? To start many of the modern fishing gear used today are not very selective
Out of all the technology mentioned in the passage, by far the most advanced has to be the LIDAR. Light Detection and Ranging is used to find objects above the ground quickly and efficiantly. It is the most useful technology used to make new discoveries. In Florida Waters Treasure Hunters, Mel Fisher created his own technique of finding underwater treasures. He calls it the mailbox system. "A mailbox is a large metal tube that is bent 90 degrees, like an elbow. The tube has a diameter several inches
atmosphere and reduce the impact of climate change. Why wouldn't we continue to explore something that covers over half of our planet? Besides the fact that our oceans take up majority of our planet, the medical benefits it has are unbelieveable. Biological and chemical materials from marine life are in use or are being developed to fight against HIV, inflammation, tuberculosis, cancer, and fungal infections. For example, a species of caribbean sponges are capable of making compounds used in producing
The Problem of Rising Acidity Levels in Oceans Ever since the industrial revolution, humans have been responsible for the releasing of carbon dioxide into the atmosphere as a result of industrial and agricultural uses. The ocean absorbs roughly a quarter of this carbon dioxide. Originally, scientists believed this to be a benefit because the ocean was removing CO2 from the atmosphere. Ocean acidification, however, began to change the chemical composition of the water. NOVA’s documentary, Lethal Seas
1.0 Introduction A sea wall is a form of coastal defense constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a seawall is to protect areas of human habitation, conservation and leisure activities from the action of tides and waves. Seawalls may be constructed from a variety of materials, most commonly: reinforced concrete, boulders, steel, or gabions. Additional seawall construction materials may include: vinyl, wood, aluminium
"On a recent afternoon, Scott McKenzie watched torrential rains and a murky tide swallow the street outside his dog-grooming salon. Within minutes, much of this stretch of chic South Beach was flooded ankle-deep in a fetid mix of rain and sea. “Welcome to the new Venice,” McKenzie joked as salt water surged from the sewers." ----- Michael J. Mishak, Associated Press June 7, 2014 at 4:24 PM EDT According to the World Bank Development Report 2013 there has been an increase in global surface
