Street, Arcata, CA 95521 Abstract Phytoplankton may be small, but they are the critical for the food web of the ocean. Because they are one of the primary producers it is important to understand how they absorb and retain energy for others to use it. Different conditions such as light and nutrients yield different outcomes. Using a fluorometer, the effects of light and nutrients absorption was measured based on growth rate and abundance of cultured phytoplankton Tetraselmis suecica. The results were
This includes phytoplankton and zooplankton. Phytoplankton are plant plankton or some are bacteria that they contain chlorophyll and want sunlight in order to grow and live. It lives in watery environments both salty and fresh. Some phytoplankton can improve nitrogen and can grow in low concentrations nitrate areas. Phytoplankton are most important to the ecosystem because it is a food
Phytoplankton and algae provide the nutrients that marine life requires to survive. Phytoplankton serve as a food source for many small marine organisms, while algae is producing oxygen that increases oxygen levels in the water, but as well as in the air for non-marine organisms to use. The warming oceans have made it harder more phytoplankton to re-produce, and excluding the Arctic and Antarctic waters, the phytoplankton level have been dropping throughout the
plankton from nekton, which include organisms that can control their movement in the water. Some planktonic organisms can be quite large, however, plankton are generally smaller than nekton. Plankton can be classified based on their feeding styles. Phytoplanktons are a very important part of ocean life. The carbon dioxide in the atmosphere is in balance with carbon dioxide in the ocean. During photosynthesis, phyto...
have proven to cause high levels of algae production. The Tampa Bay estuary has four major river basins that flow into it transporting TN and TP from the outfalls of terrestrial wastewater treatment plants and agricultural runoff. The process of phytoplankton growth which consumes the excess TN and TP in natural systems can also be related to the changing water quality levels such as dissolved oxygen (DO), salinity, available nutrient concentration, pH, water temperature and turbidity. For example,
“Oceans”, the third unit from “The Habitable Planet” series, discusses El Nino and the discovery of a new phytoplankton, and how these effect human and marine life . This paper will highlight six facts from the video, emphasizing what they are, how scientists have discovered this information, and what makes them important. In addition to these facts, this paper will explain the term “positive feedback” as briefly mentioned in the video and provide an example of this process outside of El Nino. The
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 important to understand
Nowadays, water quality becomes an increasingly important problem and draws more and more public’s attention. Water quality is used to define the chemical, biological, and physical characteristics of water (Diersing, 2009). It is a measure of the water condition relative to the requirements of one or more species and to any human need or purpose such as drinking, swimming, and fishing (Johnson et al., 1997). Degradation of water quality through different channels in different sources and different
The iron hypothesis, created by John Martin, states that if the ocean could be enriched with iron, more phytoplankton blooms could grow that would take the carbon dioxide out of the atmosphere and possibly reverse the greenhouse effect. Martin’s test demonstrated that when you germinate high-nutrient, low-chlorophyll zones in the ocean with iron, you increase the production of phytoplankton blooms, this information proves his hypothesis true. This will improve the earth by making the carbon dioxide
The concept of the microbial loop first began in 1926 by Vernadskii, who studied heterotrophic and phototrophic microbial metabolism; and understood that these systems represented a major part of total metabolism in the oceans (Pomeroy, 1988). Older techniques that scientists used for enumerating marine bacteria were by plate counts, serial dilutions and phase-contrast microscopy. These numbers represented about 10% of actual numbers and are no longer used (Azam et al, 1983). Scientists were unable

Agricultural runoff can help the Red Tides can form because they are full of nitrates that will grow phytoplankton. Phytoplankton are single celled organisms that are plant-like organisms that can form dense, visible patches near the water's surface. And when they are in a high concentration area they can produce toxins that can paralyze . They can also change colors
UV rays into the Earth's atmosphere and oceans. The safety of the planet and its organisms rests on the protection of the stratospheric ozone layer. If the depletion of stratospheric ozone continues, it will result in the deterioration of the phytoplankton which is an important base to the aquatic food chain on which most marine and animal life depends.
Ozone depletion directly affects society and the environment through increased exposure to UV radiation on humans, animals, plants and materials. Increased exposure to UV radiation can have serious adverse side effects for humans: Skin Cancer UV-B radiation can cause benign and malignant skin melanomas. A reduction in ozone levels increases the amount of UV-B radiation that can reach earths surface which would cause an increase in the number of occurrences of skin cancers, sunburns and premature

CFCs and phytoplankton exposed to UV radiation are both links between the ozone hole and global warming, but overall there aren’t many significant links between the two. Neither have a great impact on the other, but they both do have significant impacts on the environment
It is a marine phytoplankton product that has the ability to enhance your health in a big way. In fact, the guy behind this supplement used it to bring his health from poor to excellent. Oceans Alive is his company 's product that he claims will give you more energy, better
Biodiversity loss can occur in many ways and this cause is very bad for the human , and the other species and the environment. These can lead down the surviving environment and mostly everyone living in that environment will suffer. There will be global warming, causing the earth to get warm and hot. Biological diversity, or biodiversity, is the term given to describe the number, variety and variability of living organisms and how these change from one location to another, and over time. Biodiversity
using fewer fossil fuels and creating more green spaces. However, this method needs a long time for carbon dioxide level to stabilize again. Another method is to implement iron fertilization into the ocean to stimulate photosynthesis in phytoplankton. The phytoplankton will convert the dissolved carbon dioxide into carbohydrate and oxygen. Eventually, it yet has been proven to be truly effective for a large body of water in the ocean. During this time, it’s better of us to move into renewable energy
The Great Pacific Garbage Patch, which is sometimes referred to as the Eastern Pacific Garbage Patch and the Pacific Trash Vortex is a floating patch of garbage that has collected in the North Pacific Subtropical Gyre, which is located in the middle of two high-pressure areas between Hawaii and California. The majority of the garbage, which is also called marine debris, in the patch is plastic, but items made from other materials such as glass and rubber are also present. Though the garbage patch
Chlorofluorocarbons [CFCs], commonly known as Freon, are a type of organic compounds that are made up of carbon, chlorine, and fluorine atoms. Their significant properties include low volatility of approximately 0℃, together with being tasteless, odourless, non-flammable, nontoxic, and chemically stable. They have supported the society for years through the form of a refrigerant, a solvent and a propellant. Moreover, they have contributed to the industrialization of nations, especially during the
According to NOAA phytoplankton are microscopic organisms that continuously convert sunlight and nutrients into living tissue. Phytoplankton can be harmful to the bay because they at an uncontrollable rate causing harmful algae blooms when there is an abundance of nutrients. Phytoplankton also serve as the main food source for a larger but still microscopic organism named Zooplankton. Marine Bio.org did
