Marine Mycology: An Overview of Pathogens, and Secondary Metabolites Introduction and History The golden age of marine mycology occurred from 1960-1990 with the research and discovery of most of the roughly 500 species of obligate marine fungi. Much of said research was conducted from 1980-2000; this 30 year period saw the report of nearly half of the marine fungal species currently known (Jones et al. 2009; Jones, 2011). That being said, marine fungi are vastly understudied and under rated in

liked about this movie is the snow. The fact that the frigid cold could freeze your skin, crystalize your lungs, freeze Jet fuel at -200 Fahrenheit in a matter of seconds. Also it froze the ocean solid enough that it could be driven on and walked upon. It was pretty cool how they could drive across the ocean and the super deep snow and nothing happens to them. Flag poles and flags were frozen stiff at the eye of the storm and this is what all humans should have been aware of but some did not care

discouraged by many scientists claiming that Tsunamis are not tidal waves and are not caused by tides. Tsunami strikes have number of causes out of which the most common cause is “earthquake or a shift in the Earth’s tectonic plates. It is a wave of ocean caused by an earthquake, sometimes these waves are high, but not in all cases (Bryant, 2014). The enormous amount of water is taken by Tsunami to towns that destroy everything in its way. Tsunamis are also caused by underwater volcanic eruptions.

right temperatures • fresh water • food sources • places to raise their young rajan: Warmer water temperatures will cause population declines for trout, salmon and many other species that require cold water to survive. Rising ocean temperatures have already caused massive coral bleaching, leading to the collapse of these ecosystems which sustain huge numbers of fish. NEXT SLIDE Dave: people might be affected by their homes being destroyed by floods. Business owners buildings

Session – 14 Unit – VI CLIMATIC CHANGE AND GLOBAL WARMING Dr. H.S. Ramesh Professor of Environmental Engineering S.J. College of Engineering, Mysore – 570 006 Carbon di-oxide is a natural constituent of atmosphere, but now, its concentration is increasing at an alarming rate. According to an estimate, CO2 level is expected to be doubled by 2030 A.D. The term ‘Green House Effect’ is also called as ‘Atmospheric Effect’, ‘Global Warming’ or ‘CO2 Problem’. Human activities are changing the composition

a long term scale, primarily caused by the greenhouse effect and the enhanced greenhouse effect. Oceans are especially susceptible to climate change as they have not only the most climate sensitive life but also act as a massive carbon and heat sink meaning effects are felt most severely here. Climate change threatens marine biodiversity by altering the temperature and acidity of the waters. The ocean is also home to one of the most concentrated, diverse and vulnerable habitats in

composition occurs below this depth, which in most parts of the ocean, is at a depth of 4500 meters (15000 ft) 3. Why are gas hydrate deposits abundant on submarine continental margins? (Ch. 4, Section “Energy Resources”) High productivity surface waters enrich ocean floor sediments below with organic matter. Organic marine sediments provide natural gas in which pressure is high and temperature is low 4. Why are the deep ocean basins covered with red clay deposits? (Ch. 4, Section “Distribution

formation of the Earth’s Oceans? The relationship between continental drift and the formation of Earth’s Oceans comes from the plate movement that occurred in Earth which is called plate tectonics. All of the landmasses were grouped together into one vast supercontinent called Pangea. Over millions of years the land started to split into many different countries and it also divided Panthalassa, the single great ocean that surrounded the continent Pangea, into many different oceans and that’s why now we

known as the Queensland Littoral Society, has worked for decades to defend the Great Barrier Reef against things like coral mining, oil drilling, overfishing, etc. It is also the only national charity in Australia that only works toward protecting the ocean wildlife. Without this nonprofit, who knows what would become of the Great Barrier Reef and its surrounding habitats. But before I talk about this extremely amazing nonprofit, a brief history on Australia will be given. Australia’s government is
