[1] This study presents an analysis of observed data sets from multiple sources, including observations from a network of Argo floats during (2002–2003), with the aim of investigating the role of the southwest monsoon circulation in affecting the interactions between the oceanic mixed layer and the underlying thermocline in the northern Indian Ocean. Examination of the seasonal cycle of the upp...

High resolution hydrographic observations of temperature and salinity are used to analyse the subsurface circulation along the coast of North Brazil, off the Amazon mouth, between 2 S and 6 N. Observations are presented from four cruises carried out in different periods of the year (March–May 1995, May–June 1999, July–August 2001 and October–November 1997). Numerical model outputs complement th...

A phytoplankton bloom was observed in the southeastern Arabian Sea after passage of anti-S-type track Tropical cyclone ARB 06 1998, which lasted for 22 days. The dynamic mechanism investigated with high-resolution satellite remote sensing data, reanalysis data and buoy data. results show that double thermocline structure hindered uplift deep nutrients to surface before tropical arrival. During ...

Considerable drawdown of total dissolved inorganic carbon (CT) and oversaturation of oxygen (O2) within a cold (,15uC) oligotrophic eddy in the extratropical North Atlantic Ocean (46uN, 20.5uW) indicate that, despite the absence of nitrate (NO 3 ), the eddy was highly productive. Estimates of net community production using the mass balances of CT and O2 were two to five times greater than those...

[1] We analyze the temperature anomaly of the Pinatubo eruption using an exact mathematical solution of a standard energy balance model that includes coupling between the mixed layer and the thermocline. Our solution yields a short response time t = 4.4 months and a small climate sensitivity l = 0.22 C/(W/m), implying short-term negative feedback. Also, our analysis determines a value of the ef...

Objective: Soil temperature serves as a key variable in hydrological investigations to determine soil moisture content as well as hydrological balance in watersheds. The ingoing research aims to shed lights on potential of artificial neural networks (ANNs) and Neuro-Fuzzy inference system (ANFIS) to simulate soil temperature at 5-100 cm depths. To satisfy this end, climatic and...

The effects of climate change on permafrost have been well documented in many studies, whereas the effect seasonally frozen ground (SFG) is still poorly understood. We used observed daily freeze depth SFG and environmental factors data from period 2007–2016 to examine seasonal inter-annual variation SFG. quantitatively evaluated using a boosted regression tree analysis. results show that, scale...
