TYPE LOCATION: Ocean County, New Jersey, Barnegat Bay on a former inactive flood-tidal delta sand flat associated with Cranberry Inlet, latitude 39 degrees 57 minutes 12.76 seconds North and longitude 74 degrees 5 minutes 23.72 seconds West, WGS84; USGS 7.5' Topographic Quadrangle Seaside Park.
RANGE IN CHARACTERISTICS:
Landscape: Lagoon on a coastal plain
Landform: Inactive flood-tidal delta sand flats and inactive flood-tidal delta slopes
Depth to Bedrock: Greater than 60 inches
Depth to Seasonal High Water Table: Permanently submerged (some soils can be exposed on extremely low tidal cycles or spring low tides)
Water Depth: 0 to 2 meters
Rock Fragments: 0 to 10 percent, by volume in the A and C horizons and consist primarily of seashell fragments and / or fine quartzite gravels
Soil Reaction: Slightly acid to moderately alkaline throughout the profile
Other Features: Some pedons have a sequence of buried preserved surface horizons and / or former salt marsh materials below 39 inches (100 centimeters)
Range of Individual Horizons:
Ag or Aseg horizons (if it occurs):
Color--hue of N, 5Y, 2.5Y or 10YR value of 2.5 to 4, chroma of 1.
Texture--fine sand, sand or loamy fine sand.
Some pedons have very thin oxidized surface horizons often too thin to describe.
ACseg horizons (if it occurs):
Color--hue of N, 5Y or 2.5Y, value of 3 to 7, chroma of 1 or 2.
Texture--fine sand, loamy fine sand, or sand
Cg or Cseg horizon:
Color--hue of N, 10Y, 5Y, or 2.5Y value of 3 to 8, chroma of 1 or 2.
Texture--fine sand, loamy sand, sand or coarse sand to a depth of 40 inches. Some pedons have thin stratified layers of fine sandy loam or loam textures.
Some pedons have CA horizons similar in color and texture to the C horizon.
Some pedons have preserved former surface horizons (2Aseb) below 100 centimeters with heavier textures.
COMPETING SERIES:
Demas soils (tentative)--are associated with storm surge washover fan flats and slopes in coastal lagoons, on slightly higher landforms immediately adjacent to the barrier islands.
Trappe soils (tentative)--are associated with sandy mainland cove areas, mainland beaches, and submerged wave-cut platforms.
GEOGRAPHIC SETTING:
Landscape: Bay or estuary
Landform: Inactive (relict) flood-tidal delta sand flats and relict flood-tidal delta slopes
Water Depth: 0 to 2 meters (permanently submerged)
Parent Material: Sandy lagoonal deposits
Mean Annual Air Temperature: 11.1 to 14.4 degrees C.
Mean Annual Water Temperature: 11.0 to 15.5 degrees C.
Water Salinity Range: 19 to 27 parts per thousand (ppt)
GEOGRAPHICALLY ASSOCIATED SOILS:
Cottman soils--on slightly lower landforms and lagoon bottoms towards the barrier island side of estuary.
Indian River soils--on very similar flood-tidal delta landforms that are associated with active inlet areas for the estuary.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage Class: Subaqueous drainage
Saturated Hydraulic Conductivity: High to very high
Internal free water occurrence class: Very shallow 0 to 10 inches (0 to 25 cm) and permanently submerged
Flooding Frequency and Duration: Very frequent and very long as these soils are permanently submerged or exposed only during spring low tides
Ponding Frequency and Duration: None
Index Surface Runoff: Negligible
USE AND VEGETATION: These soils can support submerged aquatic vegetation primarily as Zostera marina (Eelgrass) and/or Ruppia maritima (Widgeon grass) and often provide excellent aquatic habitat. Vegetative coverage of these soils ranges from 0 to 100 percent depending upon landform. The aquatic vegetation in these areas is extremely sensitive to human disturbance and watercraft propeller damage can easily remove the vegetative coverage leaving a bare soil surface.
DISTRIBUTION AND EXTENT:
Distribution: Delaware (Rehoboth Bay), Maryland (Chincoteague and Sinepuxent Bay), and New Jersey (Barnegat Bay). MLRA 153D - Northern Tidewater Area.
Extent: Small, less than 10,000 acres
SOIL SURVEY REGIONAL OFFICE (SSRO) RESPONSIBLE: Raleigh, North Carolina
SERIES ESTABLISHED: Ocean County, New Jersey, 2016.
REMARKS: Diagnostic horizons and other diagnostic soil characteristics recognized in this pedon are:
Peraquic conditions--the zone from the soil surface to a depth of 65 inches (166 centimeters) is permanently saturated (endosaturation).
Ochric epipedon-the zone from the soil surface to a depth of 13 inches (32 centimeters).
Sulfidic materials-the zone from the soil surface to a depth of 70 inches (177 centimeters).
