Status Report on Sylvan Lake Water Quality in 2016

This is an interim report on the results of Sylvan Lake  water quality sampling between May and September 2016. Previous posts have illustrated the joint SLWSS-ALMS project in action on the high seas. The teamwork of ALMS lake technician Breda Muldoon, able crew members from the SLWSS, and boat captain Ed Thiessen of Norglenwold allowed …

Sylvan Lake Precipitation and Stormwater Runoff in 2015

How much precipitation has fallen on the watershed in 2015? Has is been lower, higher or about average? The answer, according to data from Alberta Agriculture's Hespero weather station west of Sylvan Lake we have received just about the typical historical amount. This graph shows the 2015 cumulative precipitation (red) compared to the average curves …

Heavy Rains Erode Soil and Contaminate Sylvan Lake

Recent heavy rains have caused erosion of construction sites in the Town of Sylvan Lake (TSL) and transported fine particulates into the lake through the stormwater system and Golf Course Creek. The flow discharges into Marina Bay and then into the lake as a plume of very fine suspended solids that cause water quality to …

Who’s putting all that CO2 into the air?

NASA's mission team for the recently launched OCO-2 satellite has reported preliminary results on its performance and on observations of the atmosphere at the American Geophysical Union conference in San Francisco . The goal is to map carbon dioxide concentration in the vertical column of air between the ground and the OCO-2 satellite, and to detect sources …

Total Precipitation and Sylvan Lake Level

Sylvan Lake watchers have conflicting personal opinions about lake level. This post presents some facts about the one factor that causes the lake level to rise: the Total Precipitation that falls on the watershed area each year. Other factors cause the lake level to drop, particularly seasonal evaporation and transpiration from land, crops and foliage …

Updates to and ENSO Observations from the WUWT Ocean Reference Page

Watts Up With That?

Image Credit: Monterey Marine Meteorology Division – HYbrid Coordinate Ocean Model (HYCOM)

By WUWT regular “Just The Facts”

In making several updates to the WUWT Ocean Reference Page I observed something in the Sea Surface Temperature animation above, that I’ve seen a few times before. More about that below, but first the reason for the updates. The Naval Research Laboratory Navy Coastal Ocean Model (NCOM) was “scheduled to be retired on 5 April 2013 and replaced by operational 1/12° HYbrid Coordinate Ocean Model or HYCOM.”  The “HYCOM consortium is a multi-institutional effort sponsored by the National Ocean Partnership Program (NOPP), as part of the U. S. Global Ocean Data Assimilation Experiment (GODAE), to develop and evaluate a data-assimilative hybrid isopycnal-sigma-pressure (generalized) coordinate ocean model (called HYbrid Coordinate Ocean Model or HYCOM).” Here is HYCOM’s home page of and here is the system background
