The specific surface mass balance is positive in the accumulation area and negative
in the ablation area.
It explains why, in glaciers that are mostly cold, the ice at high altitude in the accumulation zone is usually warmer than the ice at lower altitude
in the ablation zone.
The accumulation area decreased by 24.8 %, while ablation area increased by 17.7 % with nearly 6 % increase in debris - cover surface
in ablation zone in 1958 to 2011.
The North Cascade Glacier Climate Project (NCGCP), utilizes the highest density of measurements 240 points / km2 in the accumulation zone and 10 points / km2
in the ablation zone.
This narrow range indicates that late
in the ablation season the density of snowpack on North Cascade glaciers is uniform, and need not be measured to determine mass balance.
This estimate is based on the standard deviation
in ablation along 50 m long transects with ablation stakes placed 5 m apart.

Irregular / heavy menstrual bleeding can be treated
in several ways: 1) Hormonal medication (a low dose birth control pill or cyclic progestin); 2) A hormone - containing intrauterine device (the most common one used is the Mirena IUD, which manages bleeding very effectively and is placed during an office visit and lasts for 5 years); 3) Endometrial
ablation is a surgery commonly performed as an outpatient procedure; the entire lining of the uterus is cauterized (many women never get a menstrual period after an
ablation); 4) Finally, I reserve hysterectomy as the treatment of last resort — typically only when the above options have not worked for a patient.
