The journey of prehistoric human culture on the Texas coast begins with how hunting and gathering populations adapted to the opportunities and limitations of their shoreline and nearby prairie environments. All the while using limited technology strengthened by first-hand knowledge about the location and seasonal availability of important subsistence resources within their homeland. Before my bioregion is explored, its best that I depict the history of the state that I live that spreads across the millennia. When European explorers and colonists first arrived in the region, beginning in the 1500s, the indigenous coastal peoples practiced a mix of subsistence economies which included rigorous fishing in the shoreline bays and lagoons, …show more content…
The coastal population density was moderately high, and people spent much of the annual cycle living in large shoreline fishing camps that housed several hundred people during peak fishing seasons. The coastline as we see it today is, from a geologic perspective, a very recent phenomenon that dates back only about 3,000 years. In fact, prior to around 8,000 B.C., the area of the modern shoreline was high and dry, with the Gulf coast far to the east of its present position. This is because, in earlier millennia, global sea level was as much as 300 feet lower, with much of the world’s water supply inaccessible in vast continental ice sheets and montane glaciers that were far more extensive than those of modern times. The Pleistocene era, or Ice Age, had markedly lower global temperatures than those of historical times. The final cold phase of the Pleistocene was around 20,000 years ago, after which rising global temperatures caused the continental ice sheets and mountain glaciers to begin a gradual melting process, with the result that sea level began to rise rapidly over the next 10,000 years (Hester, 1995).
As sea level rose, shorelines around the world moved progressively father inland. By 8,000 B.C. the sea had inundated major river valleys along the Texas

Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.
I believe there are many factors that define culture, such as language, food, traditions from past generations, religion, and values. All of these factors have the power to influence the individuals within.
Radiocarbon dating tests reveal that sea levels had lowered more than 400 feet below their current levels as a consequence of the growth of immense ice sheets in the Northern Hemisphere during the Ice Age.
Over the past several million years sea level has fluctuated considerably higher and lower than present levels. With these fluctuations the shoreline has shifted inland and further out, onto the continental shelf, than the present shorelines. The Northern Gulf of Mexico has followed the general path of global sea level during recent geologic time including the time since the last glacial maximum. During the last glacial maximum, 20,000 years ago, the sea level dropped approximately 100m below the present level and the shoreline extended 100km onto the shelf in some locations (Donoghue, 2011). Since the last glacial maximum the U.S. coast of the Gulf of Mexico has seen a rise in sea level at a rate exceeding those seen at any other time. The rate of overall sea level rise since the last glacial maximum is 6mm a year with some periods of rise in excess of 40mm a year. The rate has slowed and stabilized over the last 6,000 years and this has allowed ecosystems and
The Olmec culture is one of the oldest cultures in Mesoamerica. The Olmecs were known as one of the oldest cultures, as well as, the mother culture of mesoamerican cultures and were estimated to be around from 1000 to 500 BC. The name Olmec comes from the Mexica cultures that came after. It was not the name that the people of this culture named themselves, the name they called themselves has been lost through history. The Olmec culture was the culture that produced rubber, and had great workmanship in which they were able to create jade masks, celts, ornaments and tools using different materials such as gold.
The Olmec are believed to be the first great Mesoamerican civilization. The city known as San Lorenzo existed around 1200BC and declined in 400 B.C. It is considered to be the first major city in ancient Mexico.
As the earth's global temperature rises, the ocean is expected to encroach upon population-dense coastal areas because of melting permafrost and the thermal expansion of the water. When water in rivers cannot flow into the
When the sea level rises, this can be due to multiple factors including climate change and subsidence. Climate change and warming reports identify that “postglacial temperature has increased 13°F in the Gulf region” (Morton 22). This is important evidence because rising temperatures coincide with rising sea levels. As sea water warms, it expands and takes up more room causing sea levels to rise. Additionally, melting glacial ice cause the rise of sea level and is due to climate warming as
The combination of these and other trends was an estimated average sea-level increase of 1.5mm per year between 1961 and 2003, which reached 2.4mm per year in the decade from 1993 to 2003. The decades prior to this trend showed only minor fluctuations in sea-level, suggesting that the current rate exceeds what could be caused by natural cycles. While the exact impact of rising oceans is difficult to determine, it is certain that the consequences will include some degree of flooding, integration of salt water into water tables, and a loss of land due to coastal erosion and submersion.6
Completing the personal cultural survey I was able to identify the way I approach my life through my eyes. Since completing this survey I have seen my worldview through my lens and the way I approach people, and my way of life. Furthermore, I have identified that my numbers were very similar to one another, and that my average score was (4). Thinking upon this I was pondering why my average score was a (4) for everything. Maybe I grade myself too harshly or become too analytical with this test because I am a very detailed person.
Since the 1950s, the amount of heat stored in the ocean has significantly increased. Ocean heat content determines sea surface temperature, it also affects sea level and currents. An overall average of the world’s oceans. Since 1880 sea level has risen at a rate of roughly six-tenths of an inch per decade. In recent years, the rate of increase has increased more rapidly to more than an inch per decade. Sea level has risen the most with an increase of more than 8 inches between 1960 and 2015, along parts of the Gulf coast and the Mid-Atlantic coast. However, sea level has decreased relative to the land in parts of Alaska and the Pacific Northwest.
What humanity faces from the ramifications of this issue is immense. This research article will seek to convey and articulate if climate change has affected the rise of ocean levels, and if so what are the detrimental affects on coastal communities. This article will also reveal what specific regions and events that are happening that are elevating ocean level rise. The objective of this research article is to inform people about the plight that humanity has found itself in and how to prevent ecological damage and along with that prepare for the coming tide.
