Descrição do ficheiro
| Descrição |
English: Brinicle formation; (1) when water freezes, most impurities are repelled from water crystals, sea ice is very porous, cavities between ice contain brine and saline water, (2) the surrounding water becomes more saline as concentrated brine leaks out. (3) Brine-rich water remains liquid, with the increase in density causes this amount of water to sink. Setting for the creation of a "brinicle". (4) Its outer edges begin accumulating a layer of ice as the surrounding water, cooled by this jet to below its freezing point, ices up as a tubular or finger shape and becomes self-sustaining. (5) The down-flowing cold jet continues to glow longer downward, and reach the seafloor. (6) It will continue to accumulate ice as surrounding water freezes. The brine will travel along the seafloor in a down-slope direction.
ไทย: การก่อตัวของนิ้วน้ำแข็ง; (1) เมื่อน้ำแข็งตัว อนุภาคที่ไม่ใช่น้ำส่วนใหญ่จะถูกขับออกจากผลึกน้ำแข็ง และเนื่องน้ำแข็งในทะเลมีรูพรุนมาก ช่องว่างระหว่างน้ำแข็งจะบรรจุด้วยน้ำเกลือเข้มข้นและน้ำเกลือ (2) น้ำโดยรอบผลึกน้ำแข็งจะกลายเป็นน้ำที่มีเกลือเข้มข้นมากขึ้น และพยายามรั่วไหลออกมา (3) น้ำที่อุดมด้วยเกลือยังคงสภาพเป็นของเหลว ด้วยความหนาแน่นที่เพิ่มขึ้นทำให้น้ำส่วนนี้จมลง เป็นการเริ่มต้นการสร้าง "นิ้วน้ำแข็ง" (4) ขอบด้านนอกของนิ้วน้ำแข็งเริ่มสะสมชั้นน้ำแข็งหนาขึ้นรอบ ๆ และรักษาระดับอุณหภูมิที่ต่ำนี้จากกระแสน้ำเกลือเข้มข้นที่พ่นออกมา ทำให้คงตัวและกลายเป็นรูปทรงท่อหรือนิ้ว (5) กระแสน้ำเกลือเข้มข้นเย็นจัดที่ไหลลงเรื่อย ๆ จนไปถึงพื้นทะเล (6) จะยังคงสร้างน้ำแข็งอย่างต่อเนื่องรอบจุดที่สัมผัสพื้นทะเล แข็งตัว น้ำเกลือนี้จะเดินทางไปตามพื้นทะเลในทิศทางที่ลาดลง และแข็งตัวเป็นแผ่นขนาดใหญ่ |
