endangered coral reef ecosystem. Coral reefs, when they are healthy, are one of the most diverse ecosystems on the planet. They contain so much life and interaction many scientists call them the "rainforests of the seas." Yet these reefs are endange Continue Reading...
The fact is that numerous rooted macrophyte structures are not full of naturally strong and healthy particles and sediments and nutrients. It is because of the restriction or absence of these particles, sediments and nutrients that the study of the Continue Reading...

LANDFORMS Barrier island beaches generally develop where: a The coast is composed of hard rock b the nearby land has a rugged topography of hills and mountains c the sea floor deepens rapidly offshore d The sea floor remains shallow for a long dist Continue Reading...
" Because of the ability to reproduce in large amounts in a small amount of time, phytoplankton are considered as the first link in the food chain of nearly all marine animals. Phytoplankton provide food for a large variety of organisms, including th Continue Reading...
Pollutants Compound Threats to Coral Reefs and What That Means for the Ocean and Us Humans POLLUTANTS AND CORAL REEFS All over the world, the existence of coral reefs in the oceans face a lot of danger caused by pollutant compounds. A lot of consi Continue Reading...
" (SD, 1) McClintock goes on to connect this to pointedly negative consequences for marine life, arguing that many invertebrates are distinctly vulnerable because their protective shells require many of the nutrients naturally available in their sur Continue Reading...
Yet, there have been transplant successes in sheltered embayments. One of the major conclusions that have been seen is that the cost of reef repair and coral transplantation is generally high but effectiveness is usually very low. Protection and con Continue Reading...
Remote sensing can be utilized in order to give succinct information regarding the arrangement and the constituents of coral reef materials. The biological and physical attributes of the water bodies in which the coral reefs exist are monitored over Continue Reading...
The contribution of these discoveries to the field is significant. It could for example contribute to a greater understanding of the origin of life on earth. Scientists for example can further study the creatures discovered around the vents for the Continue Reading...
brevis blooms are not a new phenomenon, and fish kills that result from red tides caused by K. brevis in the Gulf of Mexico have been described in the scientific literature since 1960 or so and have been reported anecdotally for more than two centur Continue Reading...
Coral reefs are often coined as the rainforests of the sea, and they are one of the most diverse ecosystems on the planet. Although they cover less than 1 percent of the Earth's surface, coral reefs house about one-third of all marine species. It Continue Reading...
Dredging the Port of Miami Dredging refers to the activity needed to be conducted for removal of unwanted deposits present in water pathways. However, even though this activity facilitates marine traffic regularity, it isn't without its drawbacks[fo Continue Reading...
Sea grass is a type of vegetation that grows on the sea floor and is only consumed by sea turtles (Green Turtles especially) and manatees. It must permanently be "cut" short in order to remain healthy, and beds of sea grass are vital breeding and de Continue Reading...
Coral reefs [...] their status, purpose, and benefit to the environment. Coral reefs serve a vital purpose in the ocean's ecological balance. Reefs provide substantial benefits to the ocean's ecosystem, to their populations, and to man. They provide Continue Reading...
Sea around Us Rachel Carson was a scientist and author who took a topic which had hitherto been only of interest to fellow scientists and opened it up to the masses. During her lifetime, she took up many causes in support of wildlife and the protec Continue Reading...
Beach Erosion: Causes and Remedies Beach erosion is the removal of sand from a beach to deeper waters such as inlets, tidal shoals and bays ("What causes beach erosion," Scientific American, 2008). Beach erosion can have a number of different causes Continue Reading...
LA Wetlands Wetlands of Louisiana are the water-saturated swamp and coastal regions of southern Louisiana. The Environmental Protection Agency says that wetlands are "those areas that are inundated or saturated by surface or groundwater at a freque Continue Reading...
As the eel gets closer to the ocean, the water of course becomes salty and there are new dangers (fishing nets) and unfamiliar eels in the water. But true to her style of providing readers with sidebar stories, the eel passes a clay cliff where "th Continue Reading...
Just as the physical properties of ocean water and lake water differ from one another in some ways but relatively similar in others, that is also the case with much of the biological life in the respective environments. On one hand, many freshwater Continue Reading...
It should not be a difficult question to answer: we must begin reducing ocean pollution and taking steps to prohibit overfishing of our ocean shallows. The plan that is formulated to address the overfishing and man-made pollutants in the coral reef Continue Reading...
3). Still there are those who hope that the billions of dollars, the energy, and the time that have been spent to protect Venice from high tides will resolve the water problems which Venice experiences every day, and that in the future there will s Continue Reading...
" Hamilton explains that while Continental Lithosphere is as much as 93 miles thick, the "Oceanic Lithosphere" is much thinner - up to perhaps six miles. Indeed, the oceanic crust makes up only 0.099% of earth's mass, according to Hamilton. Oceanic Continue Reading...
Negative Effects of Artificial Reefs Artificial reefs are man-made habitats that are created from many different materials to build new marine life communities (Rodriguez, 2004). For many years, fish and shellfish habitats have been damaged or wipe Continue Reading...
Endangered Tuna For centuries, the seas have been viewed as a limitless bounty, a continuous source of food and resources. However, decades of fishing, pollution and destruction of habitat have taken their toll. Scientists now estimate that some 90% Continue Reading...
