Monitoring stations were co-located with nearshore water quality monitoring sties and long-term seagrass monitoring transects. Monitoring stations were selected to identify watershed discharge points, coastal hydrodynamics, as well as the existing level of LBSP exposure and anticipated changes to LBSP exposure due to management actions. Nearshore monitoring stations were designated based on their land based sources of pollution management implementation status (LBSP Treatment Group), as follows: 1) LBSP Restoration stations: Located downstream where land-based pollutant management has or is being implemented. 2) LBSP Control stations: Represent a range of land-based pollutant impairments, including sites with no LBSP management, no known direct discharge of LBSP but are representative of the range of external factors that may be encountered at the LBSP Restoration stations. 3) Negative Reference stations of know significant -anecdotal and quantified- LBSP impairment. 4) Positive Reference stations of low LBSP impairment. Two replicate sediment traps were deployed at each monitoring station. Traps were constructed and installed following Storlazzi et al. (2011) with an added honeycomb baffle at the top to reduce turbulence in the trap and prevent sample disturbance by aquatic organisms. Traps were retrieved and redeployed periodically (30-Aug-22 to 6-Feb-23; 6-Feb-23 to 1-May-23; 1-May-23 to 07-Aug-23; 07-Aug-23 to 6-Nov-23; 6-Nov-23 to 6-Feb-24). In the lab, the accumulated sediment from one trap was dried and weighed to estimate accumulation rates (mg/cm2/day). The contents of the second trap were separated into coarse (<2 mm-63 um) and fine (<63 um) fractions, dried and weighed to the estimate accumulation rate, followed by a sequential loss on ignition procedure (following Edmunds & Gray 2014, Heiri et al. 2001) to assess the terrigenous, carbonate, and organic composition. Laboratory analyses were conducted at University of Puerto Rico at Rio Piedras. Please review the Culebra Sediment Trap Monitoring Work Plan (Vargas-Angel 2024) for a complete methodological description. The data presented herein was collected with financial support from NOAA Restoration Center and NOAA Coral Reef Conservation Program, and the National Fish and Wildlife Foundation (NFWF). The research questions, survey design and monitoring localities were specific to this study and the associated water quality data is unsuitable in a regulatory framework.

This ridge-to-reef monitoring framework implements a Multiple Lines of Evidence approach consisting of: 1) Monitoring of LBSP stressors that are being managed through NOAA funding including sediment accumulation at unpaved road stabilization projects, water quality monitoring at key points throughout the watershed, and watershed modeling to estimate pollutant loads into the nearshore coastal environment. 2) Monitoring of LBSP exposure through nearshore water quality and sediment trap monitoring at nearshore fixed stations. 3) Monitoring of nearshore habitat responses that is co-located with the aforementioned nearshore water quality fixed stations and includes data collection via seagrass monitoring transects. Within this context, sediment accumulation rates and composition are characterized and tracked to quantify the land-based pollutant exposure levels in the receiving coastal environment and the associated seagrass and coral reef communities, which are ultimately the focal point of the NOAA LBSP management efforts on Culebra.

Accuracy The same la instrumentation (i.e., analytical balance, drying oven, and furnace) was employed to process and analyze all samples. Handheld GPS units were used to locate sites and mark site locations. Sediment samples were processed at the University of Puerto Rico at Rio Piedras. Laboratory technician turnover subtle sample processing inconsistencies are expected. Analytical Accuracy A few of sample processing and analytical computations inaccuracies were identified which required the removal of those data points. Completeness Measure Data gaps may originate from, but not limited to sample loss due to bioturbation, sample handling, and laboratory technician turnover. Field Precision Handheld GPS units were used to locate sites. Conceptual Consistency Survey and analytical methods were consistent across all samples. This data addresses Land Based Sources of Pollution exposure monitoring, specifically sediment trap monitoring, which together with LBSP habitat response monitoring represent the basis of Culebra's Integrated LBSP Monitoring and Evaluation Framework with which to successfully assess progress and effectiveness toward achieving NOAA LBSP management goals and outcomes on Culebra.
