“…settlement rates at La Jolla are over 100 times greater than at a site located 100 km to the south (Pineda & López 2002). At smaller spatial scales, comparisons of invertebrate settlement rates among 16 sites that span 120 km of active-upwelling shoreline in the southeastern Pacific (Lagos et al 2005) have shown consistently higher settlement at a site that appears to be located in an upwelling shadow (Narvaez et al 2004). Observations of stage-specific nearshore larval distributions were not gathered during these studies.…”

“…Both methods were the linear SW algorithms successfully applied to retrieve SST data, and the SST4 measurements were evaluated including total atmospheric water vapor content. Moreover, the SST3 measurements, which were obtained with the linear SW algorithm for retrieving SST data from MODIS images proposed by Sobrino et al [37], showed a RMDS value greater than the one from the LST2 data and smaller than the ones from the LST1 and SST2(collection 6) data, i.e., 0.58 K (Figure 2). However, the SST3 measurements highlighted maximum bias and σ values greater than the ones from LST1 and SST2(collection 6) data, i.e., −3.48 K and 0.42 K, respectively ( Figure 2).…”

“…Since the brightness temperatures in MODIS bands 31 and 32 and zenith observation angles were derived from MODIS data, the SSE values in MODIS bands 31 and 32 and the W contents are required to retrieve SST measurements from MODIS images using the Equations (4), (6), and (8)- (10).…”

“…Monitoring water quality is one of the most pressing requirements for ensuring the sustainability of these valuable and vulnerable habitats [2]. Nowadays, SST measurements of coastal waters retrieved from remote images have a wide variety of applications such as: the analysis of temperature influence over benthic organisms [1,3]; the assessment of potential aquaculture sites [4]; the detection of ground water discharge [5]; the hydrographic characterization of nearshore waters [6]; the monitoring of river plumes [7], thermal plume contaminations [8], and upwelling phenomena [9]; quantifying complex thermal environments on coral reefs [10,11]; and the study of the interactions between residual circulation, tidal mixing, and fresh influence [12]. Many of these applications have stringent accuracy requirements [1,3,4,[8][9][10][11][12].…”

Split window (SW) methods, which have been successfully used to retrieve measurements of land surface temperature (LST) and sea surface temperature (SST) from MODIS images, were exploited to evaluate the SST data of three sections of Italian coastal waters. For this purpose, sea surface emissivity (SSE) values were estimated by adding the effects of salinity and total suspended particulate matter (SPM) concentrations, sea surface wind speed, and zenith observation angle. The total column atmospheric water vapor contents were retrieved from MODIS data. SST data retrieved from MODIS images using these algorithms were compared with SST skin measurements evaluated from in situ data. The comparison showed that the algorithms for retrieving LST measurements minimized the error in SST data in near-land coastal waters with respect to the algorithms for retrieving SST measurements: a method for retrieving LST measurements highlighted the smallest root-mean-square deviation (RMSD) value (0.48 K) and values of maximum bias and standard deviation (σ) equal to −3.45 K and 0.41 K; the current operation algorithm for retrieving LST data highlighted the smallest values of maximum bias and σ (−1.37 K and 0.35 K) and an RMSD value of 0.66 K; and the current operation algorithm for retrieving global measurements of SST showed values of RMSD, maximum bias, and σ equal to 0.68 K, −1.90 K, and 0.40 K, respectively.

Influence of climate and land use in carbon biogeochemistry in lower reaches of rivers in central southern Chile: Implications for the carbonate system in river‐influenced rocky shore environments

Freshwater discharge affects the biogeochemistry of river-influenced nearshore environments by contributing with carbon and nutrients. An increase in human activities in river basins may alter the natural riverine nutrients and carbon export to coastal ecosystems. Along a wide latitudinal range (32°55′S-40°10′S), this study explores the role of climate and land use in determining the nutrient and carbon concentrations in the river mouth and fluxes to adjacent coastal areas. Between winter 2011 and fall 2012, we collected monthly samples in five river mouths in central southern Chile and at rocky shore sites affected by river plumes. Basins were characterized by different land uses and meteorological conditions along this latitudinal range. Water samples were collected for pH measurements, nutrients, dissolved organic and inorganic carbon, particulate organic carbon, and isotopic signatures (δ 13 C). Our results show a north-south gradient in concentrations of nutrients and carbon. The highest concentrations were observed in the Maipo basin, which presents the highest percentage of urban-industrial activities. Nutrients and carbon contributions, in most cases, were lowest in the southern Valdivia basin, which has the least human intervention and a greater percentage of vegetation. The Biobío River had the highest nutrient and carbon fluxes, in most cases, due to its high river discharge. Our results show the influence of river plume effects on carbon and nitrogen concentrations in river-influenced rocky shore sites. Moreover, our study suggests that land use might influence some parameters of carbonate system in rivers and river-influenced rocky shore environments. River-influenced rocky shore environments may exhibit suppression in aragonite saturation state with implications for calcifiers inhabiting these marine environments.
