Abstract
Wetlands store almost 20%-25% of the world’s soil organic carbon (SOC) stock with just 4%-6% of the world’s land area. However, recent studies estimated wetland loss is to be 53% in the contiguous US. Wetlands are the most extensive reservoir of SOC, and the loss of this carbon can lead to major increases in carbon dioxide in the atmosphere. This makes monitoring changes in SOC in wetlands a critical research area. Studies on SOC mapping using remote sensing data and digital soil mapping techniques are rare, as field-sample based monitoring of carbon in wetlands can be cost-prohibitive and labor-intensive. To alleviate this problem, we present a novel cyber-architecture-based data-centric framework. This framework explores the usability of low bandwidth, continuous, and automated sensing techniques for salt marsh SOC using low-cost and wireless in-situ sensors. It is based on developing remotely operated sensor platforms capable of acquiring data from salt marsh wetlands using Nix color sensors, other soil property sensors for pH, salinity, moisture, Redox potential, temperature, and digital photographs. All these factors have been linked to SOC in the literature, and there are cheap wireless sensors available that can collect these datasets, log them through Raspberry pi or Arduino-based computing boards, and transmit them through the cloud to the lab for modeling. The SOC prediction model is validated with field soil core data analyzed for SOC in the lab. We anticipate that this approach would help us understand soil processes in lesser-known and data-scarce ecosystems such as salt marsh wetlands.
