Surface mixed and mixing layer depths

Deep Sea Research Part I: Oceanographic Research Papers, 1995
Abstract In order to understand the daily cycle of heat storage within the surface mixed layer it is necessary to distinguish between the mixed layer, the zone of relatively homogeneous water formed by the history of mixing, and the mixing layer, the zone in which mixing is currently active.

Evaluating the sonic layer depth relative to the mixed layer depth

Journal of Geophysical Research: Oceans, 2008
Using a global set of in situ temperature and salinity profile observations, the sonic layer depth (SLD) and the mixed layer depth (MLD) are analyzed and compared over the annual cycle. The SLD characterizes the potential of the upper ocean to trap acoustic energy in a surface duct while MLD characterizes upper ocean mixing.

Mixed and mixing layer depths simulated by an OGCM

Journal of Oceanography, 2008
The global distributions of the mixed layer depth h D , representing the depth of uniform density, and the mixing layer depth h K , representing the depth of active turbulent mixing, were simulated using an ocean general circulation model (OGCM), and ...

Mixing and mixed layer depths in the ocean

2021
The ocean surface boundary layer (OSBL) is one of the largest global regulators of climate. There are two definitions associated with its depth: the mixed layer depth (MLD) and the mixing layer depth (XLD). The former is estimated using vertical profiles of temperature and density, and the latter using measurements of the dissipation rate of turbulent ...

Mixed layer depth variability over the global ocean

Journal of Geophysical Research: Oceans, 2003
The spatial and monthly variability of the climatological mixed layer depth (MLD) for the global ocean is examined using the recently developed Naval Research Laboratory (NRL) Ocean Mixed Layer Depth (NMLD) climatologies. The MLD fields are constructed using the subsurface temperature and salinity data from the World Ocean Atlas 1994 [Levitus et al ...

Three‐dimensional analytical model for the mixed layer depth

Journal of Geophysical Research: Oceans, 1992
We have recently developed a three‐dimensional semi‐analytical mixed layer remote sensing model which includes the horizontal advection and diffusion processes in our previous one dimensional model (Yan et al., 1991a). The three‐dimensional (3‐D) model can be used as a supplement to the one‐dimensional (1‐D) model in the area where advection is ...

Raman Remote Sensing Of The Ocean Mixed-Layer Depth

Optical Engineering, 1983
An oceanographic Raman lidar has been shown to be an effective tool for immediate (early) applications in Navy and National Oceanographic and Atmospheric Administration (NOAA) programs. Remote sensing of the depth of the ocean mixed layer will be of significant importance both in acoustic propagation prediction and in long range weather and climate ...

Seasonal variability of mixed layer depth in Indonesian Seas

AIP Conference Proceedings, 2015
This research is conducted to analyzed seasonal variation of mixed layer depth (MLD) in Indonesian Seas using monthly temperature average data from World Ocean Atlas (WOA) 2009 with the 0.25 degree grid resolution and wind data from NCEP. The results of this study indicate that seasonal variation of MLD are closely related to seasonal monsoonal wind ...

A simple approach to evaluate mixed layer depths

Environmental Software, 1991
In this paper we present a review of the different existing methods to evaluate the mixed layer depth (zi) by using direct and simple meteorological data over a mast. Wind speed at one height in the atmosphere and temperature at two levels are the necessary values for calculating a value of the mixed layer depth.
