Underwater welding has its own rules and many regulations to be followed, it is for the underwater welder’s safety in an unfamiliar underwater environment. However, not at all time’s regulations can be guaranteed, particularly when a person’s job is underwater and it deals with dangerous electric equipment. Here are some possible hazardous factors that comprises the method of underwater
The adaptive features of animals: i. Adaptation to live in the habitat lack of oxygen A. Crayfish: Crayfish lives in fresh water stream, which is an aquatic environment. The oxygen level in fresh water upper stream is higher than the lower stream, but the oxygen concentration is still low. The gills of crayfish are much bigger than the size at first glance. They occupied under the cephalothorax carapace in branched-shape and provided a large surface area to volume ratio to carry out gas exchange. Fresh water will be pulled into the cavity by the movement of the “gill bailers”.
SWOT Analysis STRENGTHS Solid Reputation: Coral Divers Resort has developed itself to a safe and knowledgeable diving resort. Location: CDR has a beachfront location that offers divers not only diving opportunities but also the liberty to explore islands with a peaceful and quiet atmosphere. Association with PADI and NAUI: Since Greywell was a certified diving instructor from two of the well-known certified training organisations in the world; this implied the owners experience, reliability, and credibility. Land availability for future expansion: there was massive land and resource availability if Greywell thinks of expanding his resort in future.
In swimming one of the most important pieces of gear is your swimsuit. When swimming first became a sport, swimsuits were made out of a paperlike material in 1834. This material tended to absorb water and provided more drag. However over the years swimsuit developers such as speedo have attempted to create a swimsuit that is made out of a material that has less drag, helps the swimmers be more streamlined in the water and allows the swimmer to perform better in his or her races. This has led them to create one of the most effective swimsuits ever created the Full-body polyurethane swimsuit.
In the excerpt “Life of Pi”, “The Lost Island of Tamarind”, and “The Story of Keesh” they are all in an extreme environment that takes a lot of strength and mental strength. It takes a lot more mental strength than physical strength because there’s a meaning behind why your trying to stay alive, and what’s the purpose of doing all of this. They are many reason’s why these people are trying to survive. To begin with the excerpt “Life of Pi” and “The Story of Keesh” they both have many similarities.
An organism that thrives at high pressures is called a piezophile or barophile. These organisms have a waxy cell layer that helps them survive the crushing pressures found below the sea. It has been difficult for studies to be done on such organisms because of the pressure and temperature barrier. A study done on bacteria from the Mariana trench concluded that “much of deep-sea microbiology may have been done with spurious deep-sea organisms due to warming of samples” (Yayanos, Dietz and Boxtel, 1981). The pressure of the deep ocean is incredibly hard to recreate in a
There are quite plenty of people with challenging or difficult jobs, but the hardest one in my opinion would probably have to be a Marine Biologist. My uncle has a very challenging job; he works as a Marine Biologist in Cleveland, Ohio. That has to be a very challenging and difficult job because, you are basically in the middle of the ocean, and you have to be careful with all the dangerous sea animals, and all the wildlife there. A Marine Biologist is also a really hard job, because when there is a storm or something that is really bad, it’s pretty hard to control the ship.
I’m not a big fan of watching movies, but when I do, I can find interesting aspects in all genres of film. I particularly enjoy documentaries and comedies. I thoroughly enjoy learning new things, and when I am not learning I just want to view something that makes me feel good. One of the best medicines after a long, hard day is laughter. Documentaries could be placed in the fine arts academic category.
In conclusion, Marine biology is an exciting career. It is a great career because, you get to deal with the ocean and animals or organism in it. Another reason it is so great is because, the climates you live in can be different. Lastly, marine biology is very similar to oceanography, marine science, and ocean engineering. That is why marine biology is such a great
Out of many concerns of things in Alaska environmentally, one of the most daunting is the Bristol Bay dilemma. It has been a problem for very long, and seems to be getting more controversy than many other issues. This issue is about if a pebble mine should be built there or not. Many people provide the argument about how the Alaska bay doesn’t need to be put at risk especially, because it’s a valuable food source. Bristol bay is a salmon hotspot!
