Tetiaroa Society Ecostation

During a two day trip we want to get a first overview of iron concentrations on Tetiaroa, namely the dissolved and particulate fraction in the water, bound to surface sediment and accumulated in biota (sponges and or algae). For this, we first want to take small water samples (60ml) from a boat using a peristaltic pump. Ideally we would like to take samples from 10m depth and out in the blue (eg 0.5km from shore) and in the lagoon at ~3m (n=3 per site). This is very non-invasive and no disturbances are foreseen. Second, we would take surface sediment samples. We would collect samples using a push corer (4cm diameter) and make composite samples from three pushes. This would give minor disturbance to the sea floor, but no animals will be directly affected. Third, we would like to take tissue samples of sponges and algae if available. These organisms are not CITES protected and mostly excluded from animal protection laws because of their non-vertebrate nature. We would need ~10g WW per specimen, and depending on availability N=3 per species and a maximum of 12 specimen per group.
