Slide 1 | how barrier systems respond to changes in climate |
Slide 2 bullet 1 | type of systems, such as the one pictured here, which is a typical model for mixed energy systems like the ones I'll be looking at. And exactly how storms & SLR will change them |
Slide 2 bullet 2 | Where I'm going to focus, why it matters, and what the study is trying to accomplish |
Slide 2 bullet 3 | & a little bit about how this is going to happen, mainly using GPR, dGPS, and GIS |
Slide 3 click 1 | Barrier island systems important for protection against coastal erosion, 44% within 150km, $3 tril on E coast alone. SLR seems to be changing how BI systems work. My focus will be on mixed energy systems. See stable barrier works like this, as tidal prism |

And the sediment has to be deposited elsewhere, into these deltas |
Slide 3, click 2 | Which are easier to see here. So those tidal inlets widen, allowing the lagoon to become inundated with high levels of sea water, which in turn bring more sediment onto the marsh vegetation, choking it out |
Slide 4, click 1 | The main part of this project is going to be looking at the 14 barrier islands on VES. As you can see, here are those islands & in color are the various resources near them. Some previous work has been done on Assateague island, but that needs to be |
The main part of this project is going to be looking at the 14 barrier islands on VES. As you can see, here are those islands & in color are the various resources near them. Some previous work has been done on Assateague island, but that needs to be | expanded to draw any conclusions about the chain as a whole. The plan is to look in detail at 6 of the islands (asterisks). Geologically similar area. Since this type of BI system is so common to the coastal US, this study can hopefully be applied elswhre |
Slide 4, click 2 | Part of my job is going to entail mapping a similar system off the southern coast of NJ. This chain stretches from Barnegat in the north, to cape may point in the south. |
Slide 5, click 1 | The main methods of analysis are going to be GIS mapping, ground truthing using dGPS (google maps), and ground penetrating radar. We want to map where they are now using a combo of GIS and Google Earth. |
Slide 5, click 2 | Then we hope to use Ground Penetrating Radar to look into the subsurface and see how the system has changed over time. Depending on funding, in addition to these three, it would be beneficial to get several drill cores for stratigraphic analysis as well |
Then we hope to use Ground Penetrating Radar to look into the subsurface and see how the system has changed over time. Depending on funding, in addition to these three, it would be beneficial to get several drill cores for stratigraphic analysis as well | as Carbon 14 and Lead 210 dating for chronological data. These would be combined to produce morphodynamic models of stability, a 3D hydrodynamic model, and detailed high-resolution maps. All of these materials would then be distributed to local decision- |

Slide 6, click 1 | In conclusion, this information is essential to make informed mitigation decisions going forward, and with the sea level estimated to rise from 0.18 to 0.59 m by the end of this century, information like this only grows more vital as time passes |
