Intertidal zone

The Saldanha Bay Oyster Company has two different buildings where they get the oysters market ready. The first is situated by the ocean, where they deliver the oysters. The oysters are also being cleaned and assessed in this building, they are checked to see if they are fully grown and/or if they have diseases. After this process, they are taken to the second facility which is a few meters away from the first one, and in this facility the oysters are further cared for and developed, getting…

Along the shores of Delaware, the storm surge flooding threatens 12,000 people, 13,000 homes, and 46,000 acres of land in the coastal zone at an elevation below 4 feet. If global warming emissions continue to grow, it’s possible that we could see a high emissions scenario, which will be the annual economic impact of more severe hurricanes, residential real estate losses to sea level rise…

increase the pressure on these systems as on the next few decades, development of many of the main urban and economic centers is expected to center on tropical estuaries In tropical estuaries, intertidal crabs are found abundant and diverse…

The Australian coastline is a dynamic environment, dominated by ocean processes, the movement of sediments, and presence of marine ecosystems. Understanding of coastal process is required to manage while increasing demand humans place on coast. The field trip was conducted in some beaches selected (Sellick beach, Aldingga Beach, Port Noarlungga and Brighton Beach) to present a variety of types of coast, which have variations in the natural processes and human activities occurring along the…

marine or saltwater environments. They prefer a rocky habitat. Barnacles can attach themselves in dense clusters to rocks, ships and even large animals. They live on hard surfaces at all latitudes at all depths from the intertidal zone to the deep sea. Barnacles in the intertidal region spend part of their day, during low tide, without seawater around them. Barnacles can also attach themselves to living things like whales, turtles, and manatees. Barnacle larva swim secrete a glue-like substance…

The beach has three major parts: beach face, berm and back beach. The area above the water, including the intertidal zone, is known as the beach berm. Beach berm can include vegetation, such as trees, shrubs, or grasses. The most familiar characteristic of a beach berm is its type of sand or rock (Marinebio.net, 2014). Along the backshore, accumulations of wind-blown sand may form sand dunes, and when these are sufficiently stable they become consolidated by a characteristic dune vegetation, for…

Video 1 – costal erosion Boiol242 Week 3 Sandy beaches are a dynamic system that naturally experiences phases of erosion and accretion. Storm systems producing high energy waves that can rapidly erode sediments, particularly when infrequent or intense. During calmer periods, average swell waves deliver sediment back to the shoreline (beach accretion). Beach accretion is a much slower process than erosion whereby it’d take severl years for a beach to return to its pre – storm condition…

tidal zones. Species in the splash zone and higher intertidal zone such as Cyanobacteria, Snails, Lichens, Algae, and Barnacles live farthest from the ocean because otherwise their fragile physiques would become immobilized due to the vast weight of rippling oceanic waves. Harsh environmental conditions on both levels make living stressful due to the decreased amount of moisture and scorching hot temperatures. Closer to the sea in the middle intertidal, lower intertidal, and subtidal zone,…

regards to the backbone of all organisms -- ex: blue mussels (Mytilus trossulus), and the repercussions that ripple upon all those whom rely on blue mussels as a resource to live. Blue mussels (Mytilus trossulus), are commonly found in the mid intertidal zone of rocky shore lines in Alaska…

species Hartzer, A.M, 19971613, First year BSc student, Stellenbosch University, South Africa Abstract Osmoregulatory processes within two crab species are investigated in this practical. The Plagusia, an infratidal species, and Cyclograosus, an intertidal species, are investigated to determine which is an osmoregulator and which is an osmoconformer. The haemolymph was extracted after allowing the species to acclimatize to varying concentrations of seawater. The comparative melting-point…
