Mobile Bay Tool

Full Title: Expansion of www.mymobilebay.com [now known as ARCOS] for coastal Alabama resource management

This project improved and expanded an observing network and website that provides accurate real-time weather and water quality data to Alabama environmental managers and the public.

This project began in June 2017 and will end in May 2021.

Award Amount: $720,000

Why it matters: Effective management of coastal estuaries requires real-time and historical knowledge of water quality such as salinity, temperature, dissolved oxygen, and water clarity. Resource managers and stakeholders can use web-based tools that integrate this water quality data to inform decision-making in coastal waters such as when to close oyster harvesting areas due to poor water quality. Unfortunately, many Gulf of Mexico coastal regions lack web-based tools that effectively integrate available real-time and historical water quality data. However, decision-makers in Alabama have access to the Alabama Real-time Coastal Observing System (ARCOS) which provides high-quality, system wide, continuous real-time water and weather observations in a user-friendly web-based portal (https://arcos.disl.org/).

What the team is doing: The work conducted extended the spatial and temporal coverage for ARCOS and added more measures of water quality. This enhanced the usefulness of ARCOS for resource managers by providing them with additional information critical to making decisions about living coastal and marine resources in coastal Alabama. Specifically, the improvements to the ARCOS network included upgrading four older observing stations to enhance reliability and provide real-time water clarity data, and adding offshore real-time measurements of salinity, temperature, and dissolved oxygen by upgrading an existing data collection site.

Expected Outcome: This project led to improvements to ARCOS and its web portal, https://arcos.disl.org/, which receives over 7000 visitors per month who use its data to inform coastal decision-making including living resource management and recreational activities. This project  expanded www.mymobilebay.com (now known as ARCOS) to include water clarity and offshore water quality data, improving the quality and quantity of information available to support coastal management, fisheries, and recreational use in Mobile Bay. This work also supported the use of ARCOS by recreational and commercial users who rely on the data it provides for safe and efficient boating, fishing, and shipping.
