@ DocRohan: Carboxy-Hemoglobin - CO binds 250-stronger to Hgb than oxygen, so if samples were to be retrieved containing erythrocytes it should be possible to evaluate that to indicate a fire. Osmotic strengths will have the cells burst but if the Hgb is not washed out it should be possible for forensics to evaluate that, it would not interfere with the binding affinity of gasses to Hgb. Ionic strength (9% NaCl in sea vs 0.9% physiologic conditions) could interfere with the binding of CO2 to Hgb's amine-groups but that accounts for only 10% of the binding.
If there were indeed 2 pings: feasible that one signal would be carried 600 km and heard by the other device? Or maybe both boxes (voice and data) at different locations? Implications of that?
