In the previous posts, we discussed sampling porewater in the mangroves, as well as water in the Caet\u00e9 River and estuary. We concluded our research by sampling several small creeks that flow into the larger Caet\u00e9: Furo do Taici, Furo da Ostra, Furo do Meio, and Furo do Caf\u00e9.  Like the Caet\u00e9 River, these creeks are heavily influenced by tides, so we sampled each of them at both low and high tide. We collected the samples by lowering an acid-cleaned bucket over the sides of bridges, and then filtering the water using our portable pumps and filter holders described previously. We could visually observe large tidal differences in the three creeks closest to the bay, while Furo do Taici remained low relative to the rest. We observed a variety of birds, as well as bats as dusk fell in the mangrove forest. <\/p>\n\n\n\n

After 2 weeks of intense sampling, we departed Braganca at last. We collected samples from a total of 29 different stations, including mangrove porewater, Caet\u00e9 river freshwater and estuary, and smaller creeks. Two team members from Constructor University (Nico and Adrian), as well as another group member from GEOMAR (Antao), will continue directly to the M206 research cruise, which will sample Amazon and Par\u00e1 River estuary, as well as coastal water around the mangrove forests. This will provide a valuable additional dataset in parallel to the PROBRAL samples we collected.<\/p>\n\n\n\n
