Radiocarbon Datings

The aim of this work was to generate an inventory of the data on radiocarbon datings obtained from sediments of the São Paulo Bight (southern Brazilian upper margin) and to analyze the data in terms of Late Quaternary sedimentary processes and sedimentation rates. A total of 238 radiocarbon datings from materials collected using differents ampling procedures was considered for this work. The sedimentation rates varied from less than 2 to 68 cm.kyr-1. The highest sedimentation rate values were found in a low-energy (ría type) coastal system as well as in the upwelling zones of Santa Catarina and Cabo Frio. The lowest rates were found on the outer shelf and upper slopes. Our results confirm the strong dependency of the shelf currents, with an emphasis to the terrigenous input from the Río de La Plata outflow which is transported via the Brazilian Coastal Current, as well as of the coupled Brazil Current - Intermediate Western Boundary Current (BC-IWBC) dynamics on the sedimentary processes. At least three indicators ofthe paleo sea level were found at 12200 yr BP (conventional radiocarbon age) (103 meters below sea level - mbsl),8300-8800 cal yr BP (13 mbsl) and 7700-8100 cal yr BP (6 mbsl).

Objective To evaluate the influence of the altitude on the 6-minute walking test in patients with moderate to severe pulmonary disease.Methods Twenty-nine patients performed the 6-minute walk test at a pulmonary rehabilitation clinic in Santo André (above sea level), in São Paulo State, and at the Enseada Beach, in Guarujá (at sea level), also in São Paulo State. Of these 29 patients, 8 did the test both on hard sand and on asphalt to analyze if there were differences in performance during the tests. Data such as heart rate, oxygen saturation, test distance, and Borg scale were compared.Results We found no statistical difference in relation to oxygen saturation at rest before the beginning of the walking test in Santo André 94.67±2.26% and at sea level 95.56±2% (p=0.71). The minimum saturation measured during the test was 87.27±6.54% in Santo André and 89.10±5.41% in Guarujá (p=0.098). There were no differences in the performed distance between the different kinds of terrains; the distance on sand was 387.75±5.02m and on asphalt it was 375.00±6.54m (p=0.654). Regarding oxygen saturation during walking, the pulse oximetry on sand was 95.12±1.80% and on asphalt it was 96.87±1.64% (p=1.05).Conclusion Altitude did not affect the performance of the walking test in patients with moderate to severe pulmonary disease and the results were similar in both cases, on sand and on asphalt.

Study Results

Sea level (SL), wind, air temperature (AT) and sea surface temperature (SST) variations in the coastal region of Ubatuba, northern coast of São Paulo, are assessed. A Lanczos-square cosine filter, with a 40-hour window, was applied over the SL time series between 1978 and 2000, except for the period comprising 1984 to 1986. In order to study subtidal effects on mean sea level (MSL), SL numerical filtering indicated that there was a virtually complete removal of semidiurnal and diurnal astronomical tidal components over the period of study. Results indicated an average raw SL rise of 2.3 mm/year, whereas average filtered MSL was of the order of 0.7 mm/year. Despite the overall positive MSL trend, the lunar nodal cycle of 18.6 years seemed to be the explanation for the SL series pattern. Correlations between MSL and parallel wind had a maximum correlation coefficient around 0.6, with 99% statistical confidence, while MSL and perpendicular wind correlations were not statistically significant. These results may be explained by Ekman dynamics. Data records of AT and SST between 1990 and 2003 showed positive trends for both variables. During this period, AT rose about 0.087 ºC /year for the raw series and 0.085 ºC /year for the monthly time series, and SST showed a rise of 0.047 ºC /year and 0.046 ºC/year, for the raw and monthly time series, respectively. The monthly climatology for both AT and SST showed higher values in February with 27.79 ºC and 28.59 ºC for AT and SST, respectively, and the lowest in July with 21.12 ºC for AT and 21.91 ºC for SST.

The aim of this study was to analyze the sedimentation rates of suspended material and to estimate the lifetime of the Cachoeira de Cima reservoir, in Mogi Guaçu municipality, Sao Paulo State. Sedimentation chambers were used to collect samples of suspended material. Sedimentation rates for total suspended material (TSM) ranged between 0.27 and 40.70 mg cm-2 d, for inorganic suspended material (ISM), between 0.05 and 34.19 mg cm-2 d, and organic suspended material (OSM), between 0.18 and 6.52 mg cm-2 d. Sedimentation rates of TMS, IMS and OMS at the Cachoeira de Cima reservoir are higher in the rainy season. The lifetime of the reservoir is estimated at 75 years.

Local Decision Making

The METROPOLE Project is an international collaboration between Brazil, the United Kingdom, and the United States designed to evaluate local decision making processes and to provide feedback to local urban managers on possible actions toward adaption to sea level rise (SLR). The goal of the project is to help coastal communities better understand factors that facilitate or hinder their intrinsic, local decision-making processes related to planning for adaptation to risk. The test used case sea level rise to develop case studies on long-term planning by local government and society as a means to gauge the of municipalities in different settings to address possible future risks. The framework was designed by an interdisciplinary team that incorporated social and natural scientists from these three nations, and which included local government officials. This paper focuses on some of the factors that affect decision-making in the coastal city of Santos, in the state of Sao Paulo in southeastern Brazil, and provides insight on possible actions that a coastal city, such as Santos, can do to prepare for impacts of SLR.
