Hilton, D. R., McMurtry, G. M. & Goff, F. Large variations in vent fluid CO2/3He ratios signal rapid changes in magma chemistry at Loihi seamount, Hawaii.
Vent habitats are characterized by strong gradients in productivity and physico-chemical stressors, both of which tend to increase with increasing vent fluid flux.
The results indicated north-to-south variability in vent fluid composition.

The table includes longitude, latitude, and date for each vent fluid collected.
Table 1 Chemistry of low temperature vent fluid sample from Franklin Seamount, Woodlark Basin.
To examine these combined effects on energy availability, we normalized affinity to kg vent fluid by multiplying the energy with the concentration of the limited reactant, and divided by the fraction of endmember vent fluid in the mix [24].
The model calculation began with 1 kg of vent fluid and continued with addition of successive increments of seawater until a seawater to vent fluid mixing ratio of 1,000 1 was reached.
Instead the samples represented mixtures of vent fluid and seawater that are relevant for assessing exposure to macroinvertebrate organisms.
No H2S was detected in the vent fluid so sulfur was not incorporated into the thermodynamic calculations.
Aliquots of vent fluid samples from Tu'i Malila were preserved and analyzed for dissolved organic carbon (DOC) concentration.
