High-Resolution Seismic Data from New York Coastal Survey 1997

USGS cruise ALPH 98013 collected digital high-resolution seismic reflection data offshore New York and New Jersey from September 10-22, 1997. The dataset is stored in SEG-Y standard format on a CD-ROM. The project aimed to map seafloor texture, Quaternary strata geometry, and anthropogenic impacts to support coastal management decisions.

Use Cases

• Analyzing seabed texture and bed forms from seismic reflection profiles to classify seafloor environments.
• Mapping the geometry of Quaternary strata layers using SEG-Y header information and reflection data.
• Identifying areas of anthropogenic impact, such as dredging or dumping, from anomalies in the seismic record.
• Creating reconnaissance maps of the sea floor by processing the SEG-Y format data with seismic software.

Strengths

• Data collected during a dedicated 13-day USGS research cruise.
• Stored in the industry-standard SEG-Y format compatible with most seismic-processing software.

Limitations

• Dataset is over 25 years old, limiting analysis of recent coastal changes.
• Specific sample size, row count, and file size metrics are unknown.
