In situ CO and hydrogen uptake rates for recent Hawaiian volcanic depositsa
| Site | Uptake of:
|
|
|---|---|---|
| CO (mg of CO m−2 day−1) | H2 (mg of H2 m−2 day−1) | |
| I-B | 1.6 ± 0.1 | 3.9 ± 0.3 |
| I-C | 1.2 ± 0.4-2.0 ± 0.8 | 0.1 ± 0.02-1.3 ± 0.2 |
| I-D | 2.7 ± 0.4 | 0.4 ± 0.1 |
| I-E | 3.2 ± 1.6-3.8 ± 1.8 | 0.8 ± 0.2-4.9 ± 2.5 |
| II-B | 4.8 ± 2.2 | 0.6 ± 0.1 |
| II-C | 0.1 ± 0.1 | 1.9 ± 1.1 |
Rates are means of triplicates (± 1 standard error). Ranges are presented for sites with multiple determinations of activity (n = 3 to 6).
