BSC Anchorage
Anchored at the mouth of Big Sable Creek in Everglades National Park preparatory to 4-5 days field work on mangrove-associated fish and terrapins....
Location: Everglades National Park, FL, USA

Accessing Hurricane-Produced Mudflat BSC
Mudflats (open water in background) derived via erosion and habitat conversion from former mangrove forests often have a band of mangroves adjacent to the creek bank. Here a researcher accesses a mudflat at high tide to make measurements....
Location: Everglades National Park, FL, USA

Awaiting High Tide to Set Block Nets
Sampling fish within the intertidal zone of a mangrove forest requires setting a block net at the interface between forest and river at high tide, then retrieving the net at low tide. Here researchers await high tide to set the nets seen in the boat. ...
Location: Everglades National Park, FL, USA

Closing Seine Around Pivot Pole
Seining for fish in open water necessitates closing the seine quickly to avoid fish escape. Closing the seine around a pole offshore accomplishes this objective in sampling....
Location: Terra Ceia State Aquatic Preserve, FL, USA

Deploying Lift Net, Everglades National Park
Lift nets buried in the forest floor and deployed at high tide permit the estimation of fish density within flooded forests....
Location: Everglades National Park, FL, USA

Closing Seine Around Pivot Pole, Everglades National Park
Seining for fish in open water necessitates closing the seine quickly to avoid fish escape. Closing the seine around a pole offshore accomplishes this objective in sampling....
Location: Everglades National Park, FL, USA

Fish Processing in Lab
Technician processes fish samples brought in from mangroves....
Location: St. Petersburg, FL, USA

GCC BSC Set Block Net
Setting block net across an intertidal rivulet draining a hurricane-derived mudflat. Net is retrieved at low tide to obtain an estimate of fish catch. Fish density was found to be greater in waters draining natural tidal forests than in waters from mudflats formed as a result of landfall of a Cate...

Hydrological Measurements
Estimating volume of water discharged from fish sampling locations within mangrove forests is necessary to derive fish density estimates per volume. Fish density was found to be greater in waters draining natural tidal forests than in waters from mudflats formed as a result of landfall of a Categor...

Measuring Flow From a Mangrove Forest
USGS scientist measures water velocity as part of estimating flow from a mangrove forest....
Location: Everglades National Park, FL, USA

Opening Center Bag of Seine, Everglades National Park
Sampling juvenile common snook following passage of Hurricane Wilma October 2005. Storm surge from hurricane is hypothesized to have facilitated recruitment of this sportfish to presumptive Tarpon Bay nursery grounds in the following 18 months....
Location: Everglades National Park, FL, USA

End of Dry Season
Dead molluscs and raccoon tracks are concentrated in cracks in mud in the substrate of a dried-down tidal pond. Increased frequency and duration of droughts are predicted by some climate models....
Location: Terra Ceia State Aquatic Preserve, FL, USA

Seining Blocked-off Mosquito Ditch
Scientists pull a seine net through a blocked-off section of a man-made ditch to estimate fish abundance....
