Develop, support computer programs, and solve problems

as needed by resident geophysical scientists for data, signal, and image

processing. Problem solving is mostly mathematically and

statistically oriented.

Software are implemented using the Interactive Data Language from the Research Systems, Inc., C or

FORTRAN. Most developments

involve either 2-D or 3-D graphic products. Other shell scripts such as

perl and C-Shell are also used for programming

applications. For web programming, JavaScript

and perl are also used.

All the software are operating in the UNIX workstations.

Current Projects

1)

Noise Levels

(part of T-Phase) project to use the collections of the Hydrophones data

for computing the average noise levels in dB re μPa2/Hz at

different points of the oceans.2)

(underwater seismic signal) project to display T-Phase data recorded from

different instruments, to detect both biological and geological T-Phase events

(e.g. submarine volcano eruptions and whale calls) using mathematical filters,

to determine their possible locations on earth, and to produce audio from the

selected T-Phase signals.

Past Projects

BeamForming

(part of T-Phase) project to focus the T-Phase signals into a specified

directional area of interest using the existing T-Phase data collected

from stationary hyrdophone arrays.

(related to the T-Phase Project)

using Monte-Carlo method to determine the standard errors of the T-Phase

Event locations computed from a Nonlinear Least-Square Method.

project to allow users to request data through a web site by specifying

either a time range or the time of an event occur and let the program to

retrieve the data that contain the signals of the event. A perl cgi script

will prepare the users' request. Then an IDL program will retrieve the data

and notify the users when the data are ready.

project to allow users to generate a map (using

software) by entering the map boundary

in latitudes & longitudes through a web-browser.

GIS project to adopt AML & C programs from other sources for creating

ArcView projects & Arc/Info coverages.

to display sonar data (equivalent to remote sensing signals) into digital

mosaic images including orthorecification and allow various image enhancements.

Geological Photo project to plot specified data onto

selected mapping coordinates. SEABEAM

(a high-resolution bathymetric sonar mapping system)

data processing project to remove noise from the data files. PROFESSIONAL TRAINING:Designing with Java
