| 2021 | The Nature Conservatory Arlington, VA | C | $100,000 | paid | THE NATURE CONSERVANCY (TNC) HAS IDENTIFIED THE ESTABLISHMENT OF A NETWORK OF REGENERATIVE OCEAN KELP FARMS AS A MEANS OF DRIVING KELP REFORESTATION AND LONG-TERM RECOVERY IN CALIFORNIA. TNC IS LAUNCHING A DEMONSTRATION PROJECT TO ESTABLISH THE FIRST-OF-ITS-KIND REGENERATIVE OCEAN FARM ON THE NORTH COAST OF CALIFORNIA. THIS PROJECT WILL RESTORE 20 ACRES OF KELP FORESTS, VALIDATE THE POTENTIAL OF REGENERATIVE OCEAN FARMING, AND BRING BACK THE PRODUCTIVITY AND BIODIVERSITY OF THE ECOSYSTEM WHILE PROVIDING ECONOMIC OPPORTUNITIES FOR COASTAL COMMUNITIES. TNC'S GOAL WITH THIS PROJECT IS TO ESTABLISH A FRAMEWORK THAT CAN HELP RESTORE BULL KELP POPULATIONS AND THE LIVING SHORELINES THEY SUPPORT ALONG THE CALIFORNIA COASTLINE. | 202220149349100112 |
| 2021 | Virgina Institute of Marine Science (vims) Foundation Gloucester Point, VA | D | $99,206 | approved, future | AS THE EPITOME OF SATO-UMI, LIVING SHORELINE RESTORATION IS INCREASINGLY BEING CONSIDERED AS A MEANS OF REDUCING SEDIMENT AND NUTRIENT POLLUTION IN COASTAL WATERS. HOWEVER, WE LACK READILY-ACCESSIBLE TOOLS FOR COMPUTING AND OPTIMIZING THESE REMOVALS, WHICH WOULD INCREASE THEIR BENEFITS AND PROMOTE THEIR INSTALLATION. OUR OBJECTIVE IS TO DEVELOP A WEBACCESSIBLE, DECISION SUPPORT MODELING TOOL FOR STAKEHOLDERS TO COMPUTE THESE REMOVALS, VALIDATED AGAINST FIELD MEASUREMENTS IN THE LOWER CHESAPEAKE BAY. WHILE FOCUSED ON THE CHESAPEAKE, THE APPROACH AND RESULTING MODEL WILL BE WIDELY APPLICABLE TO LIVING SHORELINES IN MODERATE TO HIGH SALINITY WATERS GLOBALLY. | 202220149349100112 |

| 2021 | Duke University Beaufort, NC | C | $75,926 | paid | THE CENTRAL OBJECTIVE OF OUR PROJECT IS TO FILL KEY KNOWLEDGE GAPS IN QUANTIFYING THE INTERPLAY BETWEEN CORAL REEF RESTORATION ACTIONS AND HYDRODYNAMIC RESPONSES AT THE SHORELINE TO INFORM THE DESIGN OF CORAL RESTORATION FOR SHORELINE PROTECTION. WE WILL USE A SYSTEMATIC SERIES OF COUPLED 3D WAVE/CIRCULATION MODEL SIMULATIONS OF IDEALIZED CORAL REEFS, CORRESPONDING TO DIFFERENT CANDIDATE CORAL RESTORATION DESIGNS (E.G., VARYING CORAL HEIGHT, SPACING, POSITION ON REEF, PATCHINESS/CLUSTERING, ANTECEDENT BOTTOM ROUGHNESS) TO UNDERSTAND THE EFFECTS ON WAVE ATTENUATION, DETERMINE FORCES ON RESTORED CORALS AT DIFFERENT POSITIONS ON THE REEF, AND BREAKAGE PROBABILITIES. THESE ANALYSES WILL ASSIST IN IDENTIFYING SPECIES, CONFIGURATIONS, PLACEMENT, AND ATTACHMENT METHODS FOR THE HIGHEST POTENTIAL FOR SUCCESSFUL RESTORATION. | 202220149349100112 |
