reply: It is true that certain bacteria are able to bridge the gap between concentration fronts of oxygen/nitrate and sulfide. This is particularly true for the Thioploca rather than for Beggiatoa, and is mostly found in environments characterized with sharp gradients of oxygen and sulfide close to the sediment surface. During investigations at the Captain Arutyunov mud volcano a comprehensive ...

This is a very interesting study of the influence of frenulate siboglinids on the biogeochemistry of an active mud volcano. The authors demonstrate the alteration of oxygen, sulfide, sulfate, and methane profiles and flux rates by the activity of the frenulate worms. It also makes some strong predictions about the controls on the worm’s growth by the geochemical conditions it inhabits. This is ...

this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...

Submarine mud volcanism represents an important pathway for methane from deeper reservoirs to the surface, where it enters the benthic carbon cycle. To quantify overall methane release from the Captain Arutyunov mud volcano (CAMV) and to assess the contribution of macrobenthic seep organisms to the regulation of the benthic methane flux, we linked water column methane concentrations, seabed met...
