Understanding how wave climate variability and its trends change over time are crucial analyses required to mitigate potential wave-induced impacts and adapt coastal areas to such effects. The long-term trends and breakpoints of the wave energy flux (WEF) and its relationship with teleconnection patterns in southern Brazil were studied using ERA-5 wave reanalysis with validation using a waverider. We determined that the interannual mean WEF (WEFm) and extreme WEF (WEF98) that reaches the southern Brazil have increased over the past four decades, with a increment of 0.063 and 0.17 kW/m/year, respectively 0.63 and 0.29% per year. By the Muggeo method we determined that subperiods with increasing WEFm trends are related to the SSE and SSW quadrants and that these are also the most energetic ones and with the highest annual increment rates of WEFm and WEF98. Our results also suggest that the positive trends observed in interannual WEF values are likely related to the long term transition of cold to warm Atlantic Multidecadal Oscillation (AMO) phase in the western South Atlantic Ocean. From a coastal risk perspective, it is important to understand the relationship between climatic indices and the wave climate to support long-term coastal management policies. Abstract

Evaluating effectiveness of marine No-take Zones (NTZ) can be cost or labor prohibitive, thus comparisons to nearby unprotected areas are typically lacking. Two NTZs were evaluated, the waters surrounding Ilha Anchieta State Park and Palmas Island in Ubatuba, São Paulo, Brazil, for species richness, diversity, and abundance of ichthyofauna, comparing them with two nearby unprotected “Take” Zones. From 23 deployments using Baited Remote Underwater Video (BRUV), 737 individuals from 51 species of fish were recorded. The NTZ community composition was significantly different from Take Zones, with higher average species richness, abundance, and diversity but similar evenness. Seven species, accounting for more than 72% of the composition differences between Take and NTZs, were more abundant in NTZs. Comparisons of individual sites within each zone showed high variability for the Mar Virado Take Zone, with one site grouped with NTZs at 30% similarity. In parallel, BRUV deployed over a short period was assessed as a potential rapid, low-cost method for analyzing the effectiveness of a marine protected area, important for management of sites in low- and middle-income countries with patchy resource availability. BRUV distinguished significant community structure differences between Take and NTZs, with no difference between sites within each classification. Comparing with BRUV conducted for a longer period at two of the four study sites (MV and PA), our rapid study recorded 44.3% of total species using 28% of the survey effort. Compared with a multi-method survey as a proxy for a record of all potential species present at a third site (AI), BRUV recorded 30% of total species using 4.2% of the survey effort. BRUV showed bias towards size classes >15cm and certain feeding strategies, important to note if assessing a single target species. Overall, this rapid implementation of BRUV showed a clear difference between sites that differed in fishing protection level. Abstract

Water quality on the continental shelf off the eastern Brazilian Northeast region was investigated in two oceanographic campaigns during winter and summer, when vertical profiles of salinity, temperature, turbidity, chlorophyll and dissolved oxygen were recorded. Dissolved / dispersed petroleum hydrocarbons (DDPH) were also analyzed in sub-superficial water samples using fixed wavelength fluorescence spectroscopy methods. Shelf waters are dominated by Tropical Waters, with high salinity (> 36.5 g kg -1 ) and temperature (> 26 °C) and little continental influence. Turbidity was higher during winter, which may be due to the higher continental contribution and/or higher wave action. Chlorophyll was mostly < 1 µg L -1 and dissolved oxygen saturation was predominantly high (> 90%), but innermost costal stations were influenced by the Capibaribe estuary. Median DDPH concentrations were as low as 0.07 and 0.04 µg L -1 Carmópolis oil equivalents during winter and summer respectively, and 0.02 µg L -1 chrysene equivalent for both periods. An exception was observed off Suape Harbor (0.35 µg L -1 Carmópolis oil equiv. and 0.13 µg L -1 chysene equiv.), suggesting navigation activities as the main local source. The overall DDPH median of 0.06 μg L -1 Carmópolis oil equivalents and 0.02 μg L -1 chrysene equivalents are proposed as the baseline concentration for non-polluted coastal water for the tropical western Atlantic Ocean margin. Abstract Descriptors: Chrysene, Turbidity.
在冬季和夏季的两次海洋学活动中，对巴西东部东北地区大陆架的水质进行了调查，记录了盐度、温度、浊度、叶绿素和溶解氧的垂直剖面。用固定波长荧光光谱法分析了亚浅表水样品中的溶解/分散石油烃(DDPH)。陆架水域以热带水域为主，盐度高(> 36.5 g kg -1)，温度高(> 26°C)，大陆影响小。浊度在冬季较高，这可能是由于较高的大陆贡献和/或较高的波浪作用。叶绿素大部分< 1µg L -1，溶解氧饱和度主要高(bbb90 %)，但最内海岸站受卡布巴里伯河口的影响。在冬季和夏季，DDPH中位数浓度分别低至0.07和0.04 μ g L -1 Carmópolis油当量，以及0.02 μ g L -1 chrysene当量。在Suape港观察到一个例外(0.35µg L -1 Carmópolis油当量和0.13µg L -1乳糜当量)，表明航行活动是主要的当地来源。提出了0.06 μg L -1 Carmópolis油当量和0.02 μg L -1芘当量的总DDPH中位数作为西大西洋热带边缘未污染沿海水域的基线浓度。描述词:Chrysene，浊度。

We assessed the angling conducted in the Santos estuarine area (southeastern Brazil) between September 2012 and November 2013. The results, based on 189 interviews conducted in 38 different fishing locations, showed that shore-based anglers were predominantly residents (78%) and spent US$23 per fishing day. However, 61% of the onboard anglers were from the São Paulo metropolitan area and spent around US$100 per fishing day, generating a potentially important economic impact. Only two of the 15 variables analyzed showed no significant differences between the anglers' categories. According to the anglers' perception the possible pressure on the fishery resources and conflicts regarding resource use and areas in the face of port and industrial activities, urbanization, lack of security, as well as the anglers' time of experience, should be considered in any management measures to be proposed.
