Phytoplankton

plankton community’s abundance, diversity and dominance. In this study multiple physical and biological factors were observed in order to examine how surface plankton communities varied with distance from shore in the nearshore environment of the Southern California Bight. Through this study we have identified that small phytoplankton, predominately dinoflagellates, dominate the stratified waters off of the coast of Dana Point. As well as identifying other abiotic factors that directly affect the vertical and horizontal…

6.3 Research question #3 How do mercury stable isotopes ratio change in mercury bio-uptake and bio-magnification in an Arctic marine ecosystem? There is still debate in the scientific community about Hg trophic transfer and/or in vivo transformations lead to MDF and MIF of Hg isotopes (Bergquist and Blum, 2007; Perrot et al., 2012; Senn et al., 2010; Kwon et al., 2012; Das et al., 2009). The MDF and MIF signatures of food webs may help to identify major sources and processes leading to…

Everything that was created by the earth was made to be recomposed, recycled and reused. All of these chemicals are now effecting the animals that call the ocean their home. “No breathing species could live on this planet until the surface layer of the ocean was filled with phytoplankton”(page 347). All life on earth depended upon this simplistic organism to evolve and sustain life. Phytoplankton provides food for the fish and most importantly oxygen to breathe. Without oxygen nothing would be…

Introduction Phytoplankton require nutrients and light to survive. Certain nutrients are a limiting factor in phytoplankton competition and composition. Some phytoplankton are limited by nitrogen while others may be limited by phosphorus (Quigg, 2016). The experiment in this paper will determine if a body of water is limited by nitrogen or phosphorus by running a resource limitation assay. Nutrient levels in bodies of water may change seasonally in a natural way (Vanni and Temte, 1990).…

trash visible with the naked eye, according to National Oceanic Service and Ocean Portal, (Figure 3: Casey Chan) however the majority consists of plastics. About 90% of plastic (according to National Geographic) does not breakdown but becomes micro-plastics – small particles the size of phytoplankton. Fish are consuming these plastics,…

What is the importance of plankton in oceans and food chains? Plankton are essential in oceans and food chains worldwide. Phytoplankton specifically, are the primary producers providing food for Zooplankton, which together they formulate the foundation of the oceanic food chain. They are also a vital food source for larger animals.Phytoplankton are responsible for most of the transfer of carbon dioxide from the atmosphere to the ocean. What is the difference between phytoplankton and…

Take Home Final Exam 1. a. In my experiment there would be three experimental groups: the first would have both nitrogen (N) and phosphorus (P), the second would only have N, and the third would only have P; all three groups can be tested in order between April and mid-June where the graph shows the lake had some of the highest biomass of Diatoms, Dinoflagellates, and Green algae. The independent variables would be the N and P in each experimental group and the amount added in each setting;…

combat this problem. Geoengineering is growing in popularity as a solution to slowing and preventing future global warming. By manipulating the existing processes in the environment, geoengineering. In the case of iron fertilisation, large quantities of iron are deposited in oceans in order to stimulate a bloom in phytoplankton populations; for photosynthesis to occur, iron is needed. An increase in phytoplankton populations would greatly aid the marine food chain and be successful in removing…

Nitrogen and phosphorus are the major limiting nutrient elements in a variety of aquatic ecosystems and are altered by anthropogenic activities; such as row crops, feed lots, and humans (Elser et al. 2007). Larger inputs of nitrogen cause an abundance of phytoplankton and macrophyte production (Ferree and Shannon 2001).The purpose of this study was to examine nitrogen and phosphorus levels at Ada Hayden Lake in the comparative context of their effect on phytoplankton abundance as well as…

Nearly phytoplankton are all are able to float they all float in the upper part of the ocean where the sunlight hit the water. Phytoplankton provide food for a lot of sea creatures like wills, shrimp, snails and jellyfish. When phytoplankton get too much nutrients they might grow out of control and form harmful algal blooms. These balloons produce toxins this may have harmful effects on sea animals. Zooplankton Plankton is composed of phytoplankton and zooplankton which are on usually tiny…
