Hurricane Sandy made landfall near Atlantic City, NJ on October 29, 2012 as a Category 1 hurricane with sustained winds of 80 mph. The storm surge exceeded expectations due to coinciding with a full moon high tide, amplifying water levels by 20% and worsening coastal flooding. Beach profiles before and after the storm showed significant erosion of dunes and sand loss from beaches and nearshore areas. Preliminary estimates found New Jersey lost over 14 million cubic yards of sand due to Hurricane Sandy.

Ocean bottom seismometers (OBS) are instruments that measure tectonic movements and earthquakes from the seafloor. They were developed in the 1970s but modern versions have lower power usage, higher precision clocks, and can detect smaller motions. OBSs are used to study the structure of the Earth's mantle and crust, calculate earthquake energy levels, and predict seismic events. They are deployed for periods ranging from 2 months to over a year and have provided insights into phenomena like sea floor spreading and whale vocalizations.
This document summarizes a study examining semidiurnal perturbations ("Perts") to storm surges along the US Eastern Seaboard. The researchers analyzed tidal gauge and meteorological data from 1996-2014. They found that 22 out of 85 tropical storms produced "Perts" over 0.15m at Fort Pulaski, GA. Storms that generated "Perts" fell into three categories based on their trajectory. Wind stress, rather than atmospheric pressure, appeared to be the main driver of "Perts". Thresholds for meteorological conditions that produce "Perts" will be further investigated through numerical modeling.
The document analyzes coastal processes at Southern Palm Beach on the Gold Coast of Australia. Fieldwork and analysis found the beach is wave-dominated and highly dynamic, changing morphology frequently. Seasonal storms and tropical cyclones increase risks like beach erosion and flooding during peak tourism season. Due to unpredictable beach conditions, erosion hazards, and high maintenance costs, the document recommends against constructing a resort at the proposed site. A location further south near Currumbin Creek may be more suitable due to higher elevation and sediment accumulation.
This study examines coastal erosion in Gjiri i Lalzit, Albania. The goals are to understand the causes of erosion, quantify biological, physical and socioeconomic factors contributing to erosion, and identify sustainable management practices. Methods include interviews, topographic surveys, grain size analysis, dendrochronological analysis, and analysis of satellite images and numerical models. Preliminary results indicate erosion is driven by changes in wave patterns, land use changes like deforestation, infrastructure development near rivers, and declining river sediment transport from factors like dams and mining. Over 30 years, the coastline receded over 1 km. Future work includes additional data collection and modeling to understand erosion drivers and inform management.
This document summarizes a study applying 3D seismic refraction traveltime tomography to characterize shallow subsurface geology at a groundwater contamination site. The study area is a 95x40 meter region over an aquifer contaminated with dense nonaqueous phase liquids (DNAPLs). The goal is to image subsurface velocity structure and identify a paleochannel that acts as a trap for DNAPLs. Traveltime tomography was used to invert over 187,000 first-arrival times and obtain a 3D velocity model showing a north-south trending low-velocity feature interpreted as the paleochannel, which agrees with over 100 existing well logs. The model provides 7.5-10 meter lateral resolution to a depth of 15 meters.

This document discusses using GPS vertical positioning to monitor groundwater storage changes. It begins by explaining that groundwater mining is a global problem, and that extracting groundwater causes the land surface to rise as the total water storage decreases. It then discusses how GPS networks can detect these vertical position changes at the sub-centimeter level on a daily basis, allowing monitoring of seasonal water changes. Finally, it notes that long-term groundwater pumping can lead to both reversible and irreversible subsidence exceeding several meters, and provides examples from California's Central Valley.
This document discusses methods for characterizing groundwater storage, including traditional well measurements and satellite-based GRACE observations. It defines terrestrial water storage as all water on the land surface, and explains that groundwater often dominates variations in storage. Wells measure groundwater levels, with changes indicating replenishment or depletion over time. GRACE satellites detect changes in mass distribution and associated gravity field variations to infer changes in total water storage, including groundwater, at coarse spatial scales. The document provides examples of using both approaches to monitor groundwater in key aquifers.
The document summarizes tidal marsh restoration techniques used in the Northeast United States, including tidal reconnection projects, fill removal to restore degraded marshes, and thin-layer sediment placement to combat marsh edge erosion and plant dieback. Specific restoration case studies are described for Gooseneck Cove, RI and Pepper Creek Marsh, DE that involved culvert installation and sediment spraying to reconnect tidal flow. Larger scale fill placement projects in Jamaica Bay, NY are also summarized, where soil volumes from 1-5 feet were used to restore over 150 acres of marsh islands between 2006-2013.
This document discusses the results of the first Wave Glider experiment in the southern Tyrrhenian Sea conducted from September 12-26, 2012. The Wave Glider collected oceanographic and meteorological sensor data to characterize features of the southern Tyrrhenian Sea, including temperature, salinity, currents, and optical properties. It found that the Wave Glider was able to capture major surface oceanographic patterns that agreed with satellite data, including the coast-open sea salinity gradient and presence of a cyclone-anticyclone system. However, Wave Glider optical properties were less correlated with satellite products. Overall, the results demonstrate the emerging value of Wave Gliders for multi-platform ocean monitoring by providing high resolution data to
The document discusses methods for predicting earthquakes, which scientists have tried with varying degrees of success. It outlines several contemporary prediction methods, such as observing unusual animal behavior, changes in water levels and radon emissions, and analyzing seismic electric signals. However, the document concludes that scientists have not achieved 100% accurate predictions yet, though prediction capabilities have improved over time as more data is collected and patterns analyzed.
Monitoring surface deformation combining optical and radar sentinel data gsg ...Pavlos Krassakis
This document discusses monitoring surface deformation in New Zealand caused by a large 2016 earthquake using optical and radar satellite data. It combines differential interferometry (DInSAR) using Synthetic Aperture Radar (SAR) data and offset tracking (OT) to map displacement. DInSAR showed line-of-sight movement while OT mapped movements in east-west and north-south directions. Combining these techniques provided a more complete picture of the complex surface deformation than either method alone. The analysis demonstrated the potential of using multiple earth observation tools to study earthquake impacts.
Seismic Modeling ASEG 082001 Andrew LongAndrew Long
This document discusses tools for modeling elastic wave propagation to aid in seismic survey planning. It summarizes three main modeling techniques: recursive reflectivity methods, ray tracing methods, and full wavefield methods using finite-differencing. Ray tracing is useful for optimizing survey geometry but not reflectivity studies, while reflectivity and finite-difference methods model full wavefields and are better for amplitude studies like AVO. Integrating these modeling tools with real data and rock physics analysis allows comprehensive understanding of wave propagation for effective survey planning addressing all acquisition parameters and seismic phenomena.

This document summarizes research on modeling sea-level rise and wave-driven inundation on Laysan Island in the Papahānaumokuākea Marine National Monument. The research aims to estimate habitat loss on the island over the next century from sea-level rise and wave inundation. It finds that passive ("bathtub") inundation models underestimate impacts compared to wave-driven models. At 1.5 meters of sea-level rise, waves are expected to breach dunes and fill interior basins. The vulnerability of seabird species on the island varies depending on their habitat distribution and life histories. Overall, more complex wave-driven models should be used instead of passive models to better

The History of Coastal Flood Hazard Assessments in the Great LakesDaryl Shepard
This document discusses the history of coastal flood hazard assessments in the Great Lakes region. It provides statistics on the size and coastline of the Great Lakes. While inland, the Great Lakes can experience risks from storms similar to hurricanes, including surge, waves, and overtopping. The document outlines the processes considered in coastal flood analyses, such as wave setup, runup, overtopping, and overland wave propagation. It describes the Great Lakes Coastal Flood Study initiated in 2009 to conduct a basin-wide flood risk assessment and update guidance. The study uses a regional approach to analyze water levels, waves, and other processes to map flood hazards.
Springs in the El Rito watershed emerge in specific aspects based on the attitudes of underlying stratigraphic units, with eastward dipping Cenozoic units and westward dipping Mesozoic units controlling groundwater flow. Field work involved mapping spring locations, measuring rock dips, and water sampling to correlate springs with surrounding geology. Preliminary results found most springs emerging in the Ritito Formation, with pH and conductivity indicating inter-basinal flow between the El Rito and Canjilon watersheds. Further analysis of additional controls on groundwater flow is needed to fully test the hypothesis.

Why plan for growth and change, when it seems so much easier to simply react?
When there is a distinct and shared vision for your community - when residents, businesses and local government anticipate a sustainable town with cohesive and thriving neighborhoods - you have the power to conserve your beautiful natural spaces, enhance your existing downtown or Main Street, enable rural areas to be productive and prosperous, and save money through efficient use of existing infrastructure.
This is the dollars and sense of smart growth.
Success is clearly visible in Maine, from the creation of a community-built senior housing complex and health center in Fort Fairfield to conservation easements creating Forever Farms to Rockland's revitalized downtown. Communities have options. We have the power to manage our own responses to growth and change.
After all, “Planning is a process of choosing among those many options. If we do not choose to plan, then we choose to have others plan for us.” - Richard I. Winwood
And in the end, this means that our children and their children will choose to make Maine home and our economy will provide the opportunities to do so.

It notes the region has development opportunities but also strong, variable currents that are not well understood. It recommends a regional ocean observing and prediction system to improve safety by providing accurate current measurements and forecasts. A prototype system is now operational, utilizing drifter deployments, model runs, and weekly reports.

This document summarizes a study projecting future coastal flood risk for Massachusetts Bay using available data and numerical modeling. It presents the methodology, which includes using published hydrodynamic modeling data from the US Army Corps of Engineers and developing a high-resolution coupled ADCIRC and SWAN model. The model is validated against historical hurricanes and used to simulate storm surge and waves from a synthetic hurricane under present and future sea level rise scenarios. The results are analyzed to identify flood risk and how risk may increase with sea level rise.

Jason Winner, Conservation GIS Manager for Scenic Hudson presents on the new Sea Level Rise Mapper.
The mapper is a tool for communities and stakeholders to use to create visualizations of future scenarios of sea level rise. With these maps and information, Scenic Hudson is supporting communities' efforts to develop adaptation plans by helping them to:
- create maps of the extent and impacts of inundation and flood zone expansion
- understand the locations of key built and natural resources
- create graphics that illustrate different sea level rise scenarios in specific communities or stretches of the river
- estimate the risks to infrastructure and natural resources and the likelihoods of different inundation events
- develop alternative adaptation scenarios and weigh their cost and benefits with respect to built infrastructure and natural resources

Editor's Notes
Good morning! I hope everyone has been enjoying their experience at the GSA meeting, I know I sure have. I hope our presentation can provide you with a clear concept on how NJ is responding to the impacts of Hurricane Sandy and what can be done.
This presentation is a result of research by: The Coastal Research Center, and The New Jersey Geological and Water Survey
In the background you can see a satellite image and see just how large of a storm Hurricane Sandy really was.
(click)
Sandy made landfall near Atlantic City on October 29th at approximately 8pm with 80mph sustained winds. High tide was at 8:20 pm. Unfortunately Sandy occurred on a full moon high tide which made the tides 20% higher than normal and amplified the storm surge.
You might recall in 2011 Irene made landfall near Little Egg inlet. However, it was originally thought to have made landfall as a Hurricane but it was later downgraded to a Tropical Storm.
The background image shows the view looking north from rt. 35 North at the Herbert Street Inlet formed in Mantoloking. This is in Northern Ocean County…
(click)
Ok, so here you can see the Track of Hurricane Sandy. Surge levels were higher north of Atlantic City because prevailing winds were blowing onshore north of the
eye of the storm, geographically the configuration of the New Jersey and Long Islands’ shoreline funneled the surge onto the northern New Jersey shore, and into New York and Raritan bays.
(Read from slide)
The Background image shows the view looking east from Brick Beach. This was one of the areas where the natural gas lines connected to the homes were severed and what was left standing after the Hurricane became an inferno when ignited, much like Highly publicized Breezy Point fires in Queens, NY.
(click)
You can see in these diagrams areas where there were washovers (shown by Green arrows) and where two new inlets in the north end of Barnegat Bay were formed in Mantoloking (shown by Red Arrows). You can see that sand from the beach and dunes was washed over the entire width of the barrier spit in a number of places.
The Holgate Peninsula at the southern tip of Long Beach Island, (shown in the top right image) is a beach that has not been stabilized or modified by roads, structures, seawalls, or artificial dunes, and so provides a view of the natural response to the storm surge. In the narrow northern end of the peninsula, sand was transported over the barrier island from the ocean side into the bay creating a series of washover fans extending 1.4 miles along the length of the beach. Under natural conditions, repeated storm washovers gradually move the barrier landward, depositing sand on top of the bay and salt-marsh deposits.
Ok so the background image shows the Herbert Street Inlet in Mantoloking once it was filled in…
(click)
One of the research projects we used to analyze the storm damage is called the New Jersey Beach Profile Network or NJBPN. NJBPN was established in 1986; the motivation for this research originated from the coastal damage caused by a 1984 northeast storm and Hurricane Gloria in 1985. The lack of survey data for any New Jersey coastal region prior to the storm events restricted the State’s ability to substantiate the amount of damage and severity of the storm losses from beaches. This prevented the State from quantifying any damage for reimbursement through FEMA Disaster Declaration Funds.
NJBPN monitors shoreline and volume changes along New Jersey’s Coast, and consists of 105 beach profile sites along NJ’s shoreline which is surveyed bi-annually. The image on the left here shows each the entire Beach Profile Network.
The beach profiles are surveyed by walking the onshore portion and by swimming the offshore portion. Each profile starts at a fixed reference position landward of the dunes, and extends up and over the dunes, across the beach, and out into the nearshore to a closure depth between 12-20 feet.
Elevation and distance measurements are made at every significant change in slope along the profile (or every 25-30 feet), and X, Y, and Z data is collected using RTK-GPS and total station transit technologies to create a topographic profile.
Here’s a bit of background information about the New Jersey Coastal Zone:
(Read first 3 bullets)
The northern NJ coast in Monmouth County is carved into older geologic sedimentary units that created a sandy beach backed by a bluff of the older sediments, which eroded during serious storm events. The erosion provided new sand supplies and some gravel to the beach system, but the repeated bluff retreat produced by storms quickly became a serious problem following extensive human development during the last third of the 19th Century.
(Read forth bullet)
These islands have no natural local sand supply to add to the beach forcing the island to follow any rise in sea level by moving landward. These islands continue to be in ongoing equilibrium between storms, waves, sea level and tidal currents in spite of all human efforts to enforce stability and bring permanence for man-made development.
The background image was taken in 8th Avenue in Ortley Beach, NJ. Which is in Northern Ocean County as well. What is interesting to note here is what is not shown in this picture. This photo was taken from where a street intersection used to be. Seaward of this picture there used to be road, a sidewalk, a boardwalk, a dune, and then a beach. All of that has obviously been removed…
(click)
Another key research project used to analyze the impact Hurricane Sandy had was The Beach Dune Susceptibility Assessment. It is a GIS based dune susceptibility assessment that began in 2007 to evaluate the performance potential of beach-dune systems.
The Dune Susceptibility works by incorporating GIS, LIDAR, Photogrammetry RTK-GPS surveys for verification.
Hurricane Sandy allowed us an opportunity for a real life testing of the assessments validity
Here you can see the various spatial analytical techniques; in particular the use of photogrammetry.
Particularly beach slope, dune elevation, dune vegetation, and dune width.
Ok so here you have northern Ocean County; with site 146 to the south being the southern extent of Island Beach State Park, and site 156 to the north being Point Pleasant. Here you see the product of the dune susceptibility assessment on one of the hardest hit areas of Northern Ocean County where 14 pre-existing NJBPN monitoring sites were used to provide an accurate assessment of the storm related shoreline and beach volume changes and to test the dune assessments validity.
In the bottom right is the scale where you can see that red represents 90% foredune removal to blue which represents 10% foredune removal. Notice the significant amount of reds and oranges in this section…
Here’s a close-up look at the dune susceptibility model in one of the hardest hit locations in the state; Mantoloking near Herbert Street. You can see (in the bottom left) the before and after profile of the beach, along with the before and after photos of the site (to the right). There are a few things that are important to note here.
1st is that the dune susceptibility shows that with a 100 years storm greater than 90% of the foredune was predicted to be removed.
2nd you can see in the plot shown here in the bottom left that the entire dune was removed, confirming the prediction made by the dune susceptibility model.
3rd the before an after images do not appear as dramatic as they really are. These pictures were taken in the exact same location horizontally. Where before the storm the elevation was 20 ft. after the storm the elevation was 1 ft (NAVD 88).
Here’s another look at the location highlighted in the previous slide. Notice the red arrows showing configuration before and after Hurricane Sandy. 2 inlets opened up here one as Herbert Street (to the south) and one at Lymans Street (to the north).
Ok so here’s another site in Northern Ocean County in Seaside Park. NJ. You’ll notice that instead of the consistent red colors (which represented greater than 90% foredune removal), here you’re seeing yellow and green colors which represent 25% of the foredune being removed as a result of a 100 year storm event.
1st thing you’ll notice from the plot (located in the lower left of the screen) is that the dune survived the storm as predicted from the dune susceptibility assessment.
The 2nd thing you’ll notice visually from the pictures is that the homes that exist in both the before and after images are intact and undamaged. A significant amount of sand was lost from the dune however, in the end the dunes did what they were supposed to do and held.
So here’s another area that was particularly hard by Hurricane Sandy. The southern portion of Long Beach Island, particularly Holgate and Beach Haven.
At site 135 in Holgate (to the left) you can see from both the plot and from the before and after photos that the dune was completely removed and the entire first floor of all of these oceanfront homes has been completely removed.
Same story at Site 136 in Beach Haven.
On thing that is interesting to note that we noticed was that the shoreline positions in many of the hardest hit areas didn’t change significantly. What happened was that the storm surge came in so quickly that it immediately elevated the water level to the extent that the swash and berm were underwater and the massive waves began crashing directly onto the dunes.
The background image again shows the Herbert Street Inlet in Mantoloking while still inundated with water during Hurricane Sandy. You can see on the left the Herbert Street bridge; this is the location of the inlet highlighted earlier.
Ok so what were the approximate losses?
Cape May 2.2 million cubic yards
Atlantic 845,000 cubic yards
Ocean 7.6 million cubic yards
And Monmouth 3.3 million cubic yards.
For a total of 14 million cubic yards of sand lost.
So… How can we respond?
We have our final piece of key research that will be used to help us respond to Hurricane Sandy which was conducted by New Jersey’s Geological and Water Survey’s Offshore Resource Exploration Team who:
Located
Characterized
Quantified offshore sediment sources
To date:
1500 miles of seismic profiles
225 vibracores
Identified 32 shoals
400+ million cu yds sand
From a Multi-use data archive
On the left, this statewide coastal map shows several generations of sand source areas, identified by the Army Corps (blue arrows), the NJ Geological Survey (yellow arrows) or both.
(Click)
On the right we have a Cape May County-based thickness plots of offshore sand resource areas,
including sand volumes. Where the brighter reds and yellows represent the thickness of the sand deposits located just offshore in Cape May County.
These slides clearly show that more than enough sand exists offshore to replenish our beaches.
Here you see a sand resource delineation of an offshore shoal near Barnegat Inlet
NJGWS worked with the ACOE to characterize sites in both State and Federal waters.
This figure shows the group of seismic profiles that crossed a shoal body shown in the previous slide. You can see the shoal is highlighted in gold on each profile. Similar to an MRI of the shoal body.
In order to integrate seismic and sediment analysis; sediment cores are drilled at specific locations to:
1. Determine sediment character and thickness…
2. And to provide additional regional geologic data
Grain size samples are collected at 30-cm intervals from a 6-m long core. These close-spaced samples provide precise feedback on lithologic changes down-core, as seen in the grain-size curve at the lower right.
Understanding the geology of shoal formation and morphology informs how we determine sand thickness and quality.
In the case of the Barnegat Inlet shoal (highlighted earlier), the base of the shoal is composed of Holocene-aged interbedded sands and muds deposited as sea-level rose after the Last Glacial Maximum. Overlying sand deposits from ebb-tidal deltas and longshore sediment transport have been sculpted by submarine currents and flooded by subsequent sea-level rise.
If one sets a minimum thickness of 3 meters sand as a perimeter, as shown in the figure above, the shoal resource area contains approximately 64 million cubic yards of sand.
As shoals are identified, it is important to note other uses or potential hazards.
Other offshore designations include Essential Fish Habitat (shaded gray), and commercial and recreational fishing areas.
Hazards include unexploded ordnance (UXO) from historic firing fans from WW II gun emplacements that blanket Delaware Bay between Delaware and NJ.
So, what this means is that although a significant amount of sand exists; it is not always easily accessible.
The image shown in the background is the eventual end result of all of the research we’ve presented to you toady. With sand being hydraulically pumped back onto New Jersey’s beaches to help restore our damaged beaches and coastal communities.
Fill projects already planned, underway, or completed to note:
Cape may city slated for: ½ million cu yds
Lbi slated for - 3 million cu yds
Atlantic City & Ventor - 1 million
Brigantine has already been pumped
Avalon – will be touched up
Stone Harbor – we be filled in the spring
Ocean City – Currently pumping
Asbury park to manasquan, and Sea Bright will be receiving: !0 million cu yds. of sand
Unfortunately Northern Ocean County & LBI are having easement issues, but that’s a whole other can of worms…
Thank you very much and with that I’d be happy to answer any questions you might have?
