MAIA, A. P. de; OLIVEIRA, S. R. de M.; MOURA, D. J. de; SARUBBI, J.; VERCELLINO, R. do A.; MEDEIROS, B. B. L.; GRISKA, P. R..
ABSTRACT: Thermal comfort is of great importance in preserving body temperature homeostasis during thermal stress conditions. Although the thermal comfort of horses has been widely studied, there is no report of its relationship with surface temperature (TS). This study aimed to assess the potential of data mining techniques as a tool to associate surface temperature with thermal comfort of horses. TS was obtained using infrared thermography image processing. Physiological and environmental variables were used to defi ne the predicted class, which classifi ed thermal comfort as ?comfort? and ?discomfort?. The variables of armpit, croup, breast and groin TS of horses and the predicted classes were then subjected to a machine learning process. All variables...

Thermal comfort is of great importance in preserving body temperature homeostasis during thermal stress conditions. Although the thermal comfort of horses has been widely studied, there is no report of its relationship with surface temperature (T S). This study aimed to assess the potential of data mining techniques as a tool to associate surface temperature with thermal comfort of horses. T S was obtained using infrared thermography image processing. Physiological and environmental variables were used to define the predicted class, which classified thermal comfort as "comfort" and "discomfort". The variables of armpit, croup, breast and groin T S of horses and the predicted classes were then subjected to a machine learning process. All variables in the...

An Assessment of Urban Heat Island Effect using Remote Sensing Data. OceanDocs
Wang, Guiling; Jiang, Weimei; Wei, Ming.
Characteristics of urban heat island (UHI) effect and its cause are investigated by using MODIS data in April 2004. Surface parameters from the MODIS data have surface temperature (ts), albedo(a), and normalized difference vegetation index (NDVI). Their heterogeneities over urban and rural area are analyzed based on land cover classification, and their relations are also presented in order to explain the UHI effect. The results show that there exists obvious the UHI effect. Ts over urban areas are by 10.83 % higher than those over rural area,and NDVI and a over urban area are by 62 % and 18.75 % less than those over rural area, respectively. Surface temperature has significantly negative correlation with NDVI and their correlation coefficient is -0.73....

An Ocean Theme for the IGOS Partnership OceanDocs
The Integrated Global Observing Strategy Partnership (IGOS-P) established, in 1999, a thematic approach to the implementation of the IGOS. Recognising that other themes will emerge, the “Ocean Theme” was chosen to be the “pathfinder” in this approach and an Ocean Theme Team was assembled to formulate guidance. One goal of the Ocean Theme Team is to consider and study the full range of current and planned observations, while identifying potential gaps in future observations that might compromise ocean observational records. This document presents a proposed set of long-term ocean observations and identifies a number of challenges for the improvement of knowledge about both the oceans and observing techniques. The overall strategy is to create an observing...

Análisis de cambios en los afloramientos en el Pacífico ecuatorial este, durante eventos El Niño Oscilación del Sur OceanDocs
Perugachi Salamea, C..
The ocean reanalysis Simple Ocean Data Assimilation (SODA) 2.2.4 is used to explore the changes in upwelling from normal conditions to either El Niño or La Niña conditions. Physical and termodynamics variables from the reanalysis are used to explore the structure and behaviour of El Niño Southern Oscillaion (ENSO) events. The results of this analysis show that sea surface temperature (SST), entrainment velocity, wind stress, mixed layer depth, wind stress curl, and heat content anomalies are in general agreement with ENSO theory. Interestingly, the distribution of upwelling based on the entrainment velocity is very patchy, which led us to explore zonal and meridional sections of vertical velocity. We used three methods to compute changes in upwelling...

Aspectos generales sobre la estructura térmica superficial del mar, de la zona comprendida entre el golfo de Penas y la boca occidental del estrecho de Magallanes OceanDocs
Boré, D.; Barbieri, M.A.; Catasti, V..
This study was carried out within the Project Cimar-Fiordo 2. The general objective was to describe the sea surface temperature in the zone between 46º LS and 52º LS, and from the 73º 52’ LW to the 76º 30’ LW, considering the channel and fjord zone. The analysis was based on satellite images of sea surface temperature. The images used came from the AVHRR radiometer of the NOAA satellite, from the year 1995 to 1998. The cartographic representation and the analysis of the seasonal variability of the sea surface temperature was made using the software of the Geographical Information System (GIS), named IDRISI. The zone was with clouds during all the period of study, mainly in autumn. With the available images it was possible to observe a big difference...

Beneficio económico de la caballa (Scomber japonicus) con relación a la temperatura superficial del mar en el área de Mar del Plata. OceanDocs
Perrotta, R.G.; Hernandez, D.R..
The temperature that limits the presence of schools of Argentine chub mackerel Scomber japonicus was found to be around 19°C in the Mar del Plata area Buenos Aires prov., Argentina. At higher values, most shoals leave coastal waters in direction to the mid-shelf. An inverse relationship was observed between catches per unit of effort CPUE and sea surface temperature. The highest CPUE values corresponded to temperatures lower than 19°C. Beyond that value, the possibility of obtaining a CPUE higher than the unit is nearly null and the low standard deviation means it is unlikely to reach high CPUE values. The economic profit per minute of each daily cruise was estimated using a case study carried out with a single vessel pilot with mean structural and...

Izzo, A.; Boccanfuso, J..
The composition of the fleet is analyzed. The boats range 50-200 HP of engine and have 9-16 m in length overall. Most of the boats have been improving their equipment (echosounders, new engines) since 1980. An inverse relationship was found between sea surface temperature and CPUE as measured by mackerel catch permit time spent on fishing gounds. Yields are negligible over 20°C with a optimum of 20°C.

ALVES, H. M. R.; VOLPATO, M. M. L.; VIEIRA, T. G. C.; MACIEL, D. A.; GONÇALVES, T. G.; DANTAS, M. F..
In Brazil, coffee production has great economic and social importance. Despite this fact, there is still a shortage of information regarding its spatial distribution, crop management and environment. The aim of this study was to carry out spectral monitoring of coffee lands and to characterize their environments using geotechnologies. Coffee fields with contiguous areas over 0.01 km2 within a 488.5 km2 region in the south of Minas Gerais state were selected for the study. Spectral data from the sensors OLI/Landsat 8 and the Shuttle Radar Topography Mission from 2014 to 2015 were obtained, as well as information on production areas, surface temperature, vegetation indexes, altitude and slope, were gathered and analyzed. The results indicate that there is...
