Wedding Joey Lecky Ocean Tipping Points (OTP) 20170314 This layer represents the phosphorus flux coming from onsite sewage disposal systems (OSDS) (e.g., cesspools and septic tanks). OSDS point data were obtained from the University of Hawaii at Manoa (UH) (Aly El-Kadi) and the State of Hawaii Department of Health (DOH) (Bob Whittier) that estimates nitrogen flux from each property, or Tax Map Key (TMK) parcel, with OSDS. The Ocean Tipping Points (OTP) project converted the points to raster by summing nutrient flux values within 500-m pixels. A Focal Statistics tool was then used to calculate the total flux within a 1.5-km radius of each offshore pixel. Units are in grams per day per km squared. The area of interest is from the shoreline of the Main Hawaiian Islands extending 5 km offshore and 1 km inshore. This layer was developed as part of a geospatial database of key anthropogenic pressures to coastal waters of the Main Hawaiian Islands for the Ocean Tipping Points (OTP) project (http://oceantippingpoints.org). Ocean tipping points occur when shifts in human use or environmental conditions result in large, and sometimes abrupt, impacts to marine ecosystems. The ability to predict and understand ocean tipping points can enhance ecosystem management, including critical coral reef management and policies to protect ecosystem services produced by coral reefs. The goal of the Ocean Tipping Points Hawaii case study was to gather, process, and map spatial information on environmental and human-based drivers of coral reef ecosystem conditions. -160.29941254176182 -154.68250665384699 22.279162574823264 18.848703274150445 http://pacioos.org/metadata/browse/hi_otp_all_osds_phosphorus.png Sample image.
