2.10 study guide Essay

The upper zone, also known as the high tide zone, does not have enough water to sustain large amounts of vegetation.[8] The predominant organisms are anemones, barnacles, hermit crabs and limpets. The rock pools in this area are inhabited by large seaweed and small fish.

Christopher Columbus, an Italian sailor, voyaged the Atlantic ocean and discovered for himself the “New World” in 1492. The three ships Columbus sailed on are named the Pinta, the Santa Maria, and the Nina. Although Christopher Columbus is Italian, he carried out his work for Spaniards. Columbus used many forms of navigation including the system of dead reckoning, a magnetic compass, a nocturnal, and a sand glass. However, much of the technology sailors use in today’s time, such as an Electronic Chart Display Information System (ECDIS), a gyro compass, and a clock, would have given better assistance to Columbus in order to navigate his location. Therefore, those technologies and tools sailors put to use in today, would have been most beneficial to Christopher Columbus before he died.

The Tidal zones consist of splash zone, high water neap tide, low water neap tide, high water spring tide, low water spring tide, mid tide level and the splash zone and sub littoral zone. All of these tidal zones can be determined by which indicator organisms/animals are living there. For an example the splash zone is the highest of all zones and the organisms that are generally living there are noddiwinkles. If you spot a lot of honeycomb barnacles and blue-grey periwinkle’s then you are most likely in the high water tide zone and water only covers this zone at high tide. White tube worms are indictor organism the mid tide level zone and is covered by water for half of the day. There’s also the low tide zone which is engulfed in water for the majority of the day expect at low tide, you can determine this zone by finding indicator organisms such as sea squirts. The final tidal zone is the sub literal zone and this is always under water the indictor organism’s living here are brown tubeworms and striped girdled chiton.

When you're in the north woods of Maine, you can use this information to orient yourself. Even without a compass or GPS you can find your way. How?

Intertidal (mud) flats are shielded intertidal and shallow sub tidal areas (Quinn, 2014), with significant ecosystems that provide a diversity of highly productive, environmental habitats that are essential sources of food for fish during times of high tide, and for birds in low tide. The sediment composition of intertidal flats depends on the “interactions between the physical, chemical and biological processes” (Widdows, et al., 2004), but the sediment if mainly fine particles and mostly muds. The sediment itself can also either have vegetation growth or be a completely bare flat region. (Quinn, 2014).

GPS gives the distance without calculation and gives you idea of the weather condition. Quadrant is a down grade to the Gyroscopic Compass. Quadrant helps you find the north but can be effect but earth magnetic field. The Gyroscopic Compass is always pointing to the real northern star and dont use the earth magnetic field to find the northern star. Sunglass was more harder to to keep up with time you had to turn the glass every hour. The ditigal clock is hand free and you dont have to turn it every hour. Columbus had to use his own eye site to delect something but he could only see so far. Radar of would delected something miles away without having to keep watch 24/7 of ships surrounding. Columbus got off course often and had to correct himself but with Long Range Navigation Columbus could of found where his Ship was and got back on course. If Columbus had a Depth Sounder he would of be able to see under the water to make sure he didnt hit nothing and even could see the fish under the water for Columbus could catch them for

Most of these items are related to the study of heavenly bodies and the subject of astronomy. The Celestial globe is used to observe the positions of the stars and other celestial bodies. The Two Quadrant are used to read time, it allows the height of the sun and the angle to the horizon to be calculated. A sundial is an instrument used to measures apparent solar time, by measuring the position of the shadow of the sun as it changes through the day. The Torquetum is an object used to determine the relative position of heavenly bodies and tell the time. According to the experts, the sundials reveal that it is 10:30 am on April 11,1533. This tells us that exact date and time of Dinteville?fs visit to London.

Emerita analoga (E. analoga), commonly known as sand crabs, colonies can be found buried just beneath the surface along Pacific coastal beaches, most popularly located on the California coast. Emerita analoga shares many similarities the common land crab, such as a similar name and a hard protective shell. Despite this, Emerita analoga is not related at all to its more modern namesake. E. analoga’s evolutionary fitness is intertwined with the physical structure and seasonal movements of the intertidal biome, which is unique to the swash zone. The modern day E. analoga’s progressive physiology is very closely linked to Old World E. analoga structure and function. E. analoga’s interconnected dependency on the consistent cycle of ocean currents

A study to investigate how abiotic conditions at different tidal heights affect biodiversity at Cranberry Cove, NS.

The intertidal zone is a severe environment that has various stressors and forces which act on organisms that are not found in strictly marine or terrestrial environments. This environment is unique due to the constant fluctuating water levels which exposes organisms to air and the forces of crashing surf that only animals and plants with special adaptations are able to withstand. Despite all of these environmental conditions, these species are able to survive and reproduce within extreme environments.

This essay examines the question: How does GPS rely on geometry and trigonometry now that there are satellites? Has the function of geometry and trigonometry in triangulation and navigation changed since satellites were

Ever wonder what fascinating creatures there are in the Intertidal zone? Or what kinds of adaptations they use? Almost all plants that are algae live in this incredible zone. Some other names for this amazing zone are the High Tide Zone, Mid Tide Zone, and Low Tide Zone. The Intertidal Zone is also called the shallow ocean zone, and has a lot of tide pools. This zone stretches from the surface to 660 feet, and you can find jellyfish, crabs, fish, and sea turtles. Adaptations are a species ability to change to its surrounding to survive. Even though it is hard living in the harsh, Intertidal Zone, there are three amazing organisms that survive these conditions using cool adaptations, and they are the purple sea urchin, the starfish, and the jellyfish.

In the seventeenth and eighteenth centuries clock making was a vital European technology, and London was at its cutting edge. As a maritime nation, the British were concerned with one problem in particular: they could make clocks that kept very good time as long as they stayed perfectly still but not when they were shaken about, and particularly not on board a rolling ship. If you wanted to sail, it was impossible to keep a precise record of time. And at sea, if you can’t tell the time, you don’t how far east or west you are. It is relatively easy to calculate latitude – your distance north or south of the equator – by measuring the height of the Sun above the horizon at noon; but this won’t let you calculate longitude – your position east or west.

Sea anemones feed from the surrounding water by catching small micro-organisms in their tentacles. For this reason, anemones need constant water to survive which is why none were observed in the boulder area as an area with constant water cannot be guaranteed. Sand is another factor which is present in the boulder area, but not in the rock pools. Sea cucumbers were thriving closer to the low tide mark in the boulder area, yet none were observed in the rock pool area. Sea cucumbers are almost always found laying spread out across the sand, with their feeding tubes out, browsing along the sand bed. This is the feeding habit of the sea cucumber and it would not be able to carry out this habit without the presence of sand. It is shown time and time again by the presence and habits of specific organisms in each area that the abiotic factors of each area affect the ability for an organism to survive in that system.

The investigation of these tidal zones showed that most of the organisms are not evenly distributed. The tidal organisms are often hidden in cracks, shades and gullies to prevent them from being dislodged by the wave action or desiccation.
