What does ABSD mean in COMPANIES & FIRMS
American Bottom Survey Division, more commonly referred to as ABSD, is a division of the St. Louis District of the United States Army Corps of Engineers (USACE). Established in 2003, the division is responsible for surveying and mapping the rivers and lakes in the American Bottom region, located in Southern Illinois. Its mission is to ensure all clients receive accurate and reliable survey data, including equipment needs and boundary lines. This important task helps create efficient navigation plans and flood-control structures for both commercial and recreational use.

Surveying
The topography of the American Bottom region can be divided into three distinct areas: river and lake bodies; levees; and islands. Through its expertise and state-of-the-art technologies, ABSD collects data through hydrographic surveys that measures the shape of rivers, lakes, streams, wetlands, rocky outcrops, islands, and other features associated with water resources. This information forms the basis for determining navigational depths along waterways or floodplain boundaries used by engineers when developing public works plans or emergency response plans for natural disasters like floods. Additionally, ABSD also collects data from aerial photography or remote sensing techniques to create detailed contour maps that describe elevation changes over large geographic regions.
Essential Questions and Answers on American Bottom Survey Division in "BUSINESS»FIRMS"
What is ABSD?
ABSD stands for American Bottom Survey Division. It is a research project funded by the National Science Foundation and the U.S. Geological Survey to investigate cultural and paleoecological change in the Lower Mississippi River Valley from 12,500 BC to AD 1800. The project focuses on both human and environmental changes during this period.
How long has ABSD been in existence?
ABSD has been active since 2015, when its first field season began. The project aims to finish in 2021 after six full field seasons of survey, excavation and laboratory analysis.
Who is involved with the ABSD project?
The ABSD project involves many partners from various institutions across the United States, including universities, museums, government agencies, and non-profit organizations. Additionally, many local communities have participated in connecting with the past through outreach events and programs.
What areas does ABSD research focus on?
The primary areas of research for ABSD focus on cultural change over time among early Native American populations as well as changes in flora, fauna and aquatic environments across different sites within the study area.
How are archaeological sites chosen for investigation through ABSD?
Sites are identified by geophysical survey using near-surface geophysical techniques (e.g., gradiometry) along with remote sensing data collection (e.g., light detection and ranging or LiDAR). Potential locations are then tested further through shovel testing excavations before large-scale excavation can begin at a site.
What methods/tools do archaeologists use to study sites as part of the ABSD project?
Archaeologists conducting work within the scope of the ABSD project follow professional standards outlined by various organizations related to archaeological research methods. Common tools used include excavation techniques such as hand trowels or shovels; mapping instruments such as frame grids or total stations; recording techniques such as photography or sketching; sampling techniques such as flotation or coring; laboratory analysis of artifacts; and archival research.
Are there any ways for members of public to get involved with ABSD?
Absolutely! In addition to volunteer opportunities available with various partner institutions working on this research project, there are also community programs designed to engage members of public in activities that connect them with their local environment's past history like archaeological scavenger hunts content creation regarding site interpretation initiatives.
What kind of artifacts have been uncovered so far by researchers working on this project?
So far researchers have uncovered a variety of artifacts such as pottery sherds, stone tools (such as blades or projectile points), animal bone fragments, pieces of shellfish shell middens (shell middens are ancient trash piles containing evidence of what people ate), fire cracked rocks indicating old campfires nearby where people cooked food over thousands of years ago.
Final Words:
As an essential component of USACE's mission to promote safe navigation on our nation's waterways while protecting aquatic ecosystems at the same time, American Bottom Survey Division plays a critical role in ensuring accuracy and reliability when it comes to collecting data related to rivers, lakes, streams and other features in this region. With their surveys conducted using high-tech instruments paired with traditional surveying methods coupled with knowledge garnered from decades of experience working on these waterscapes provides invaluable insight on how best to protect them now and into future generations.
