July 27 The expedition begins. The R/V Seward Johnson is mobilized in Ft. Pierce, FL.  
  July 28 Ever wonder what it is like to live the life of a stinking vase sponge? Several organisms live inside these "living hotels" in a unique commensal relationship, where one party benefits while the other is not significantly affected.
July 29 Where there are rocks, there is life! Using the JSL II's powerful manipulator arm rock samples covered with thick mats of brightly colored algae, soft coral, barnacles, and tube worms are collected and examined.  
  July 30 Today we are diving on Jacksonville Scarp, a reef 30 miles north of the St. Augustine Scarp. We are seeing vermilion snapper, greater amberjack and a type of grouper called scamp. Submersible dives on habitats frequented by these species will help us to better understand reproduction in reef fishes.
July 31 Using side scan sonar scientists collect information about the structure and composition of the seafloor. This data is critical to recreational and commercial fishermen as hard-bottom areas provide habitat for many species of reef fish.  
  Aug 1 Since characteristics of fish can change, or appear differently on the surface, the science team must use a combination of body shape, pigment patterns and colors, and shape and location of fins to properly ID fish while underwater.
Aug 2 Lionfish are spotted during routine dive operations. Although this fish is an amazing site, with its venomous spines, it is charaterized as an invasive species, not usually found in the South Atlantic Bight. Read today's log.  
  Aug 3 The Johnson Sea-Link is an amazing piece of technology. During this expedition, it is using two different types of bottom samplers. Read about both of them in today's mission log.
Aug 4 Scientists are using the Young Grab to retrieve sediment samples. Read about how this technology works, and what it tells the science party, in today's mission log.  
  Aug 5 Thus ends the first leg of the Islands in the Stream 2002: Exploring Underwater Oases. Read about how reef fishes are managed, and ideas for their protection.
