Introduction

The U.S. Geological Survey (USGS) deployed a 

temporary monitoring network of water-level and barometric 

pressure sensors at 224 locations along the Atlantic coast 

from Virginia to Maine to continuously record the timing, 

areal extent, and magnitude of hurricane storm tide and 

coastal flooding generated by Hurricane Sandy (fig. 1). 

These records were greatly supplemented by an extensive 

post-flood high-water mark (HWM) flagging and surveying 

campaign from November to December 2012 involving 

more than 950 HWMs. Both efforts were undertaken as part 

of a coordinated federal emergency response as outlined by 

the Stafford Act under a directed mission assignment by the 

Federal Emergency Management Agency (FEMA). 

Hurricane Sandy Storm-Tide Monitoring

Hurricane Sandy approached the coast of New Jersey 

near Atlantic City on October 29, 2012, as a Category 1 

hurricane on the Saffir-Simpson Hurricane Wind Scale 

(National Weather Service, 1974). The large size of the storm 

created a wind field along to the coast that posed significant 

storm tide impacts. Storm tide, as defined by the National 

Oceanic and Atmospheric Administration (NOAA; National 

Oceanic and Atmospheric Administration, 2008), is the 

water-level rise generated by a combination of storm surge 

and astronomical tide during a coastal storm.

Given the historic magnitude of the storm and the 

expected scale of the resulting econonic damages and human 

hardship, and likely need for timely flood information on 

which to base both recovery operations and rebuilding efforts, 

FEMA mission assigned the USGS to deploy storm-tide 

monitoring instruments to characterize the height, extent, and 

timing of storm tides better than could be accomplished by 

existing USGS or NOAA observational fixed-place networks. 

In response, a total of 162 water-level and wave-height sensors 

were deployed at 147 locations during October 26–29 prior 

to landfall. This represented the second largest deployment 

of storm-tide sensors, behind only Hurricane Irene which 

made landfall in the same vicinity in August 2011. To supplement the records provided by these instruments, FEMA also 

mission-assigned the USGS to conduct an extensive HWM 

campaign. The resulting database of 950 HWMs following 

Sandy was the single largest HWM recovery effort in recent 

USGS history. During and after the storm, data from both 

efforts were collected and relayed immediately for display 

on the Storm-Tide Mapper, which allowed FEMA and other 

emergency management officials to examine the data and 

best direct federal response activities. Data collected from 

this event also permitted the evaluation of the performance of 

storm-tide models for maximum and incremental water level 

and flood extent, and the site-specific effects of storm tide on 

natural and anthropogenic features of the environment.

The locations of water-level and wave-height data 

collection were selected to augment existing tide-gage 

networks and to ensure adequate monitoring in areas forecasted to have significant storm tide. After Hurricane Sandy 

made landfall in New Jersey, sustained winds increased as an 

effect of an additional storm approaching from the west. The 

combination of storms, timed with the full-moon high-tide on 

October 29, exacerbated storm-tide flooding along the New 

Jersey, New York, and Connecticut coastlines, and caused 

significant backwater to occur far inland along the Delaware 

and Hudson Rivers. Storm effects along the Hudson River 

were measured as far inland as Albany, New York.

Figure 1. Locations of storm-tide sensors deployed for Hurricane Sandy, October 2012.
Hurricane Sandy Storm-Tide Monitoring 3

A total of 224 temporarily deployed sensors were 

used for Hurricane Sandy, 162 water-level and wave-height 

sensors were deployed at 147 locations (fig. 1). An additional 

62 sensors were deployed at additional locations that recorded 

barometric pressure at 30-second intervals, expressed in 

pounds per square inch (table 1). 

Of the 162 water-level sensors, 145 sensors were 

programmed to record water pressure at 30-second intervals, 

and 9 sensors recorded wave-height measured every 2 

seconds, both expressed as water level in feet above the North 

American Vertical Datum of 1988 (NAVD 88) following 

surveys completed during sensor recovery. A typical sensor 

installation is shown in figure 2. An example of water-level 

elevation and barometric pressure data collected is shown in 

figure 3. An additional eight locations were rapid-deployment 

gages (RDG) instrumented with real-time telemetered sensors 

that recorded water-level elevations and meteorological data 

every 15 minutes during the hurricane and transmitted hourly 

to USGS Webpages (table 1; fig. 4). 

At the 147 locations, 8 sensors (7 water-level and 

1 wave-height) were co-located as redundant sensors for 

quality-control purposes, and an additional 7 wave-height 

sensors were co-located with storm-tide water-level sensors 

(162 water-level sensors total). Of the 162 sensors, 7 waterlevel sensors were lost or the structure they were attached to 

was damaged during the storm, and 5 sensors (4 storm-tide 

and 1 wave-height) did not record storm tide either due to a 

lack of water-level rise or because the sensor was installed too 

high above the water. Two RDGs were destroyed by the flood.

Data were collected and processed following protocols 

established by McGee and others (2006) and expanded upon 

by McCallum and others (2012), which included correcting 

water pressure for changes in barometric pressure and salinity. 

Quality-control checks were made by (1) deploying redundant 

sensors at a subset of sites, (2) comparing water levels 

computed from temporary sensors to water levels recorded 

at nearby USGS streamgaging and NOAA and USGS tidal 

stations, and (3) comparing elevations to independent highwater marks where possible. In the aftermath of the storm, 

653 independent HWM locations were surveyed relative to 

NAVD 88 from Virginia to Massachusetts, with particular 

emphasis in New Jersey and New York where the impacts 

of the storm were the most pronounced. Multiple HWMs 

were flagged at some locations. Any HWM was considered 

an independent location if separated by more than 1,000 feet 

distance from other HWMs. An additional 297 HWMs were 

flagged throughout Connecticut, Rhode Island, and Massachusetts but not surveyed due to a lack of funding.

Data Presentation 5

Elevation Surveys

The water-level data collected by the sensors were initially 

referenced to points on permanent objects near the water-level 

sensors in order to establish a temporary datum. After the 

storm, survey-grade Global Navigation Satellite Systems 

(GNSS) equipment (fig. 5) was used to determine the elevation 

above NAVD 88 of the reference points and HWMs, per 

Rydland and Densmore (2012), and the water-level data were 

adjusted accordingly to yield elevations relative to NAVD 88. 

Some of the water-level sensors for this study were placed 

in the same locations used during the USGS storm-tide data 

collection for Hurricane Irene (McCallum and others, 2012), 

so the water-level sensors were referenced to existing reference points using differential-level surveys or graduated steel 

tapes. GNSS equipment relies on GEOID models to determine 

elevations above NAVD 88. The GEOID09 model was used for 

consistency within the deployment area, and all elevations in 

this report were derived using the GEOID09 model. 

National Geodetic Survey (NGS) benchmarks throughout 

the study area were surveyed for vertical control. Table 2 lists 

the GNSS-derived elevations using the GEOID09 model for all 

NGS benchmarks surveyed during this study and the published 

NGS elevations from the datasheets, which can be can be 

accessed at http://www.ngs.noaa.gov/cgi-bin/datasheet.prl. 

(Tables 2–6 are in the back of the report.)

Data Presentation

The data from the Hurricane Sandy storm-tide network 

constitute an extensive collection of continuous water-level 

records documenting a single, landfall hurricane. The data can 

be used to evaluate the performance of storm-tide models for 

maximum and incremental water level and flood extent, and 

for site-specific effects of storm tide on natural and anthropogenic features of the environment. The data are available in 

tab-delineated, ASCII format by site for each sensor by using 

a USGS interactive storm-tide mapper at http://water.usgs.gov/

floods/events/2012/sandy/sandymapper.html. 

Digital photographs for selected locations are available 

on the interactive mapper. Data for each sensor include location, date, time, water level, and barometric pressure, with the 

data-processing date provided in the file header. Data for each 

HWM include location, description and quality of the mark, 

and elevation.

A list of the 162 water-level and wave-height sensor 

locations and the peak storm tide recorded at each is presented 

in table 3. Locations were categorized as storm tide, riverine, 

or wave height as a result of data-collection intervals and 

proximity to the ocean. Riverine sites can be influenced 

by upstream runoff from inland flooding. These temporary 

sensors were deployed to augment long-term monitoring 

networks operated by the USGS (table 4) and NOAA (table 5). 

All HWM data collected by the USGS immediately after 

Hurricane Sandy are listed in table 6. The reference points and 

HWMs were surveyed to a vertical accuracy of 0.26 foot at the 

95-percent confidence level and within 10 feet horizontally, 

except for Union, Middlesex, and Monmouth Counties in New 

Jersey. The vertical accuracy in these counties is 0.47 foot at 

the 95-percent confidence level. The elevations derived from 

the GEOID09 model in these three counties are 0.2 to 0.4 foot 

lower than the published NGS elevations, resulting in a lower 

accuracy (table 2). The accuracy is computed based on the 

National Standard for Space Data Accuracy method documented in Federal Geographic Data Committee (1998).
