The Flandrian interglacial or stage is the name given by geologist s and archaeologist s in the British Isles to the first, and so far only, stage of the Holocene epoch the present geological period , covering the period from around 12,000 years ago, at the end of the last glacial period to the present day. As such, it is in practice identical in span to the Holocene. Present climatological theory based on analysis of Milankovitch cycles forecasts that the present Flandrian climate should decline in temperature towards a global climate similar to that of the ice age. The current global warming phenomenon could have the effect of postponing this downturn. ref http www.sciencemag.org cgi content summary 297 5585 1287 sciencemag.org An Exceptionally Long Interglacial Ahead? ref The Flandrian began as the relatively short lived Younger Dryas climate downturn came to an end. This formed the last gasp of the Devensian glaciation , the final stage of the Pleistocene epoch and is traditionally seen as the latest warm interglacial in a series that has been occurring throughout the Quaternary geological period . The first part of the Flandrian, known as the Younger Atlantic, was a period of fairly rapid sea level rise, associated with the melting of the Fenno Scandian, Scottish, Laurentide and Cordilleran glaciers. Fjords were said to be formed during the Flandrian Transgression when U shaped valleys were inundated with water.

for Stadial theory in sociology Sociocultural evolution Stadial theory A stadial is a period of lower temperature s during an interglacial warm period separating the glacial period s of an ice age . Such periods are of insufficient duration or intensity to be considered glacial periods. Notable stadials include the Older Dryas and Younger Dryas stadials and the Little Ice Age . An interstadial is a warm period during a glacial period of an ice age that is of insufficient duration or intensity to be considered an interglacial. Generally, interstadials endure for less than ten thousand years and interglacials for more than ten thousand. The Eemian Stage , which lasted from about 130,000 to 114,000 years ago, was the last interglacial prior to the present Holocene Epoch geology epoch .

Interglacial periods that occurred during Pleistocene times have been recently put under investigation, in order to better understand our present and future climates. In fact, paleoclimatic interpretations often depends on observations drawn from the study of modern historical processes. In order to better estimate the natural range of climatically important mechanisms, it seems crucial to attempt detailed comparisons of the present interglacial i.e., the Holocene with previous warm periods of the Quaternary , such as Marine isotopic stage 11 hereafter MIS 11 for the sake of brevity . Similar orbital configurations and comparable atmospheric greenhouse gas concentrations considering only the period before the beginning of the Industrial Revolution, i.e. 1800 AD ca. have led to the suggestion that MIS 11 is a suitable, possibly the best, geological analogue for the natural development of Holocene and future climate.

In the science of tephrochronology , the Saksunarvatn tephra is volcanic ejecta that formed an Tephra layer ash layer that is useful in dating Northern European sediment layers that were laid down during the Boreal period Boreal period, the warm climate phase that followed the cold snap of the Younger Dryas as the earth made the transition from the last Pleistocene glaciation to the current interglacial , or Holocene . This was a period of rapid climatic transitions around the North Atlantic, some of which took place during a matter of decades. Similar effects are evident in independent palaeoclimatic reconstructions obtained from pollen zone s, marine and Ice core ice core records, but these sequences cannot be reliably calibrated with one another. The ash layer from a specific volcanic event, deposited simultaneously over wide areas, provides a common reference point or time marker called a horizon, which establishes simultaneity in the sequences wherever that layer is found this set of techniques is called tephrochronology . Radiocarbon dating establishes a date for the Saksunarvatn tephra of ca 10.200 years BP calibrated, during the late Pre Boreal climatic phase of rapid warming. The volcanic event happened on Iceland. The name commemorates the site where the ash layer was initially recognized, Lake Saksunarvatn on the island of Streymoy in the Faroe Islands , described by Waagstein and Johansen, 1968.

In places the crest of the tuff ring has been flattened off by bulldozing during subdivision in the 1990s. The tuff ring is breached to the north east, presumably by the sea during the Last Interglacial Interglacial warm period , about 130,000 years ago, when the sea level was 5 6 m above the present. The present floor of the crater is about 5 m above present high tide level and slopes down to the edge of Harania Creek estuary on the Manukau Harbour . After eruption, Boggust Crater would have become a freshwater lake, before it was breached by the sea to become an intertidal lagoon for a few thousand years, rather like Panmure Basin today. The sea level dropped about 120,000 years ago and the crater became a swampy depression until 1 m of fill was added and drainage installed to make it a recreational sports field.

Unreferenced date December 2009 Orphan date February 2009 A perched coastline is a fossil coastline currently above the present coastline. It can be produced by one of two factors. 1. Perched coastlines can be created by higher sea levels in the past than today. For example during the last Ice Age interglacial period, climates were significantly warmer than today, and thermal expansion of the oceans, together with increased melting of glacier s, meant that sea levels were higher than they are today. This has created evidence of perched coastlines all around the world. 2. Perched coastlines can be created through coastal uplift from local geological processes, particularly along the edges of rift valley s or subduction zone s of tectonic plate s. This second kind of perched coastline is important archaeologically as it can expose human remains that would otherwise be below sea level.
