In Photo: Juvenile mangroves on eastern berm of Jim Foot Key, April 2019.  Mangroves are intermingled with saltwort, the dominant live vegetation on the damaged berms, and standing dead mangroves.  Grid is 25 cm high.  The question is whether these trees will mature fast enough to protect the berm from rising sea level. 

In Photo: Interior mudflat on Jim Foot Key covered with saline water, April 2019.  Stumps of dead mangroves (reportedly damaged by Hurricane Donna in 1960 (Craighead, 1962)) are visible projecting from the water.  Shadowed areas below the water are underwater grasses typically found in Florida Bay, now growing inside

In Photo:  Berm of Jim Foot Key about 1.5 years after Hurricane Irma. The red circle indicates the same position as shown in the April 2014 photo. The mature mangrove trees have not recovered from the storm.  

In Photo: Eastern berm of Jim Foot Key, April 2019.  This photo taken from Florida Bay, looking in toward the center of the island (now covered in water).  The arrow points toward a breach in the berm, first noted in 2014, but the cut has deepened significantly after Hurricane Irma, and the island interior

Mangroves on the outside of a playa within Florida Bay.

Thawing permafrost on various peatlands in Alaska. Permafrost thaw results in ground subsidence and inundation that kills black spruce and other understory plants living on the permafrost plateau. The black spruce forests found on permafrost plateaus are replaced with sedge- and moss-dominated bogs and fens, altering the ecosystem structure and function.

After a long day collecting cores, the team of scientists watch the sun set over the Florida Bay.

Mangroves grow along the outside of a playa, one of may in the Florida Bay area.

Cores were collected from various areas of thawing permafrost-peatlands in Alaska. Permafrost thaw results in ground subsidence and inundation that kills black spruce and other understory plants living on the permafrost plateau.

An outcrop of quartzite within the Roanoke Rapids terrane near Coleman Lake.  Laser ablation inductively coupled plasma mass spectrometry U-Pb geochronology on detrital zircon grains within this unit (conducted by the USGS LA-ICPMS Lab in Denver) will provide critical and precise geochronologic age control as a geologic framework model is developed and compiled
