Overview

Recently, 250-m resolution MODIS images acquired by the Earth Observing System Terra and Aqua Satellites during sunglint conditions allowed

us to survey high-frequency nonlinear internal solitary wave occurrences on a near-global scale (Christopher Jackson, 2007). It is possible to

detect internal solitons packets leaving the generation area during fortuitous conditions: minimum cloud cover, near-specular reflectance

pattern of sunlight off the ocean surface (sunglint) and strong oceanic stratification.

The Rapid Response system was developed to generate user-specified, geo-referenced MODIS Subsets and MODIS Near Real-Time (Orbit Swath)

Images. We acknowledge the use of Rapid Response imagery from the Land Atmosphere Near-real time Capability for EOS (LANCE) system

operated by the NASA/GSFC/Earth Science Data and Information System (ESDIS) with funding provided by NASA/HQ.

Between year 2008 and 2013 we acquired MODIS Aqua/Terra images from the Eastern Caribbean Sea during fortuitous conditions. About 30

images show clear surface patterns associated with internal soliton packets departing from the Aves Ridge, The images KML files in Google Earth

allowed us to measure and characterize the internal wave packets. The displacements of some packets were tracked in sequential images

allowing estimating their speeds (Alfonso-Sosa, 2012). The image catalog shows the following information next to the image. It includes: image

date (UTC), original image file name, inter packets distance (IPD) in kilometers, leader soliton separation distance (LSS) in kilometers, soliton

packet name with suffix, distance from source point in kilometers (Dist.), time period between images in seconds and the speed expressed in

meters per seconds . The suffix corresponds to the image year day. The origin point for our distance measurements was selected at the southern

tip of the prominent Aves crest, the origin coordinates were: 14° 03’ 12” N, 63° 36’ 35” W. Negative Dist values means the wave is located East

of the origin. The first figure show the image crop frames of the interest areas.
