Grotta Grande
del Vento - Grotta de Fiume
(Frasassi Caves) - Italy
Megan Porter lighting up the passage. Field work took
place in August, 2005.
Scott Engel helping Robin Reger gear-up for a short rappel
to a H2S-lake. Marco Menichetti patiently waits.
Getting ready to climb up out of this smelly hole - the Ramo Sulfureo where we have been for 3 hours!
Marco and Scott working on testing the pH of acid
droplets in the Pozzo di Cristali.
Taking pH measurements in the sulfidic stream.
Sampling water and microbial mats at resurgence spring
to look for "Epsilonproteobacteria"
(See "Epsilonproteobacteria" research
website).
Trying to sample water and microbial mats in small pothole.
This research has been partially supported by the:
Group photo after sampling the Ramo Sulfureo,
Frasassi Caves, Italy. From top-left: Peggi Palmer, Megan Porter, Robin
Reger, Scott Engel
From lower-left: Marco Menichetti, Art Palmer, Mike, Annette Engel.
Robin "catching" microbial filaments for DNA
analysis.
Where are Annette's legs?
Annette taking dissolved ion measurements (e.g., H2S, O2,
NO3-, NH4+, Fe2+/Fe3+),
as well as recording all the field data from others.
Robin sampling the microbial mats in Ramo
Sulfureo stream.
Microbial filaments (biofilm) on limestone
in sulfuric stream.
Ramo Sulfureo; white area in lower part of photo, underwater, is
limestone covered by biofilms.
Scott taking pH of condensation.
Scott taking pH of condensation; reading pH
0.8!!!
