The Land Beneath the Ice: The Pioneering Years of Radar Exploration in Antarctica

為了解決Antarctica Antarctic的問題，作者Drewry, David J. 這樣論述：

A wondrous story of scientific endeavor--probing the great ice sheets of AntarcticaFrom the moment explorers set foot on the ice of Antarctica in the early nineteenth century, they desired to learn what lay beneath. David J. Drewry provides an insider’s account of the ambitious and often hazardou

s radar mapping expeditions that he and fellow glaciologists undertook during the height of the Cold War, when concerns about global climate change were first emerging and scientists were finally able to peer into the Antarctic ice and take its measure. In this panoramic book, Drewry charts the hist

ory and breakthrough science of radio-echo sounding, a revolutionary technique that has enabled researchers to measure the thickness and properties of ice continuously from the air--transforming our understanding of the world’s great ice sheets. To those involved in this epic fieldwork, it was evide

nt that our planet is rapidly changing, and its future depends on the stability and behavior of these colossal ice masses. Drewry describes how bad weather, downed aircraft, and human frailty disrupt the most meticulously laid plans, and how success, built on remarkable international cooperation, ca

n spawn institutional rivalries. The Land Beneath the Ice captures the excitement and innovative spirit of a pioneering era in Antarctic geophysical exploration, recounting its perils and scientific challenges, and showing how its discoveries are helping us to tackle environmental challenges of glob

al significance.

最後一次冰消期的南大洋動力學和上升流 ：模擬研究

為了解決Antarctica Antarctic的問題，作者高甘 這樣論述：

末次冰消期之（距今 (BP) 之前的 9 至 21000 年 (kyr)）氣候演變是了解氣候驅動力與反饋作用如何影響地球氣候的最佳時間。 南大洋通過湧升流與海洋表層水交換養分和富含碳的深海海水，並將表層海水的有機碳與無機碳帶入深水循環，上述過程在冰期氣候系統中發揮著重要作用. 然而，對推動南大洋湧升流的物理機制的理解仍在發展中. 本論文采用海氣耦合地球系統氣候模式, 在海盆尺度上研究了南大洋末次冰消期海洋-大氣-海冰-陸地表面的氣候演化時間序列. 此外, 本研究的重點是通過一系列的單一強迫力敏感實驗了解冰川變化在軌道日照、溫室氣體、大陸冰蓋和海洋淡水注入強迫力中對經向翻轉環流和南大洋洋流動力

學的作用.這項研究表明, 從南半球近地表西風帶、風切和南極海冰覆蓋範圍看來，從末次冰盛期 (19 至 20 kyr BP) 到海因里希事件 1（Heinrich I 14.7 至17.6 kyr BP）至 Younger Dryas（11.5 至 12.5 kyr BP事件，南大洋上升流主要是由風應力驅動的。然而, 在全新世開始期間(9 到 10 kyr BP), 結果顯示南大洋上升流增加而風切卻下降, 這表明尚有其它替代機制調節南大洋之湧升流強度。本研究的特別之處在於強調南極海冰融化和海水鹽度分層反饋的變化調節了區域海水密度並對南大洋的密度和浮力通量做出了改變, 並影響了南大洋的洋流動力.這

項研究表明：解釋全新世開始期間湧生流強度的增加.單一強迫力敏感性實驗顯示, 軌道日照的變化對南大洋末次冰消期間的湧升流強度為主控因素。北半球融冰造成的淡水注入通量在經向翻轉環流變化的上下分支中起主導作用.本論文的主旨在於了解南半球西風帶、海洋和南極海冰在南大洋緯度的動態聯繫，並指出最後一次冰消期間南大洋湧生流的變化是共同受控於風切應力與海水浮力通量的變化.

Race to the Bottom of the Earth: Surviving Antarctica

為了解決Antarctica Antarctic的問題，作者Barone, Rebecca E. F. 這樣論述：

Equal parts adventure and STEM, Rebecca E. F. Barone’s Race to the Bottom of the Earth: Surviving Antarctica is a thrilling nonfiction book for young readers chronicling two treacherous, groundbreaking expeditions to the South Pole--and includes eye-catching photos of the Antarctic landscape.Rivetin

g! I raced to the end of this book! --Alan Gratz, New York Times bestselling author of RefugeeIn 1910, Captain Robert Scott prepared his crew for a trip that no one had ever completed: a journey to the South Pole. He vowed to get there any way he could, even if it meant looking death in the eye. The

n, not long before he set out, another intrepid explorer, Roald Amundsen, set his sights on the same goal. Suddenly two teams were vying to be the first to make history--what was to be an expedition had become a perilous race. In 2018, Captain Louis Rudd readied himself for a similarly grueling task

: the first unaided, unsupported solo crossing of treacherous Antarctica. But little did he know that athlete Colin O’Brady was training for the same trek--and he was determined to beat Louis to the finish line. For fans of Michael Tougias’ The Finest Hours, this gripping account of two history-maki

ng moments of exploration and competition is perfect for budding scientists, survivalists, and thrill seekers. A nail-biting tale of adventure, tragedy, and superhuman determination--and also a luminous example of how our present lives are shaped by our immeasurably deep connection to our past. --El

臺灣北部潮境公園紅藻細翼枝菜 (Pterocladiella capillacea)之真菌菌相硏究

為了解決Antarctica Antarctic的問題，作者車孝正 這樣論述：

目前與藻類上真菌多樣性相關之研究還在初期階段，只有少數研究其分佈及多樣性，特別是在海洋大型藻類上。細翼枝菜 (Pterocladiella capillacea)為北臺灣終年生長的優勢紅藻物種，本研究旨在調查生長於細翼枝菜上可培養之內/外生真菌多樣性，主要目標為：(1) 調查自基隆潮境公園採集之健康及死亡細翼枝菜上之真菌多樣性；(2) 比較分離菌株使用之培養基種類以及表面殺菌方式對細翼枝菜上真菌多樣性之影響；(3) 探討細翼枝菜上真菌之季節性變化。本研究自2013年5月至2014年5月期間，每兩個月至臺灣基隆潮境公園採集健康及死亡之細翼枝菜藻體。健康及死亡之細翼枝菜藻體片段以三種不同方式做表

面殺菌或漂洗：(1) 4%次氯酸鈉溶液；(2) 70%酒精；(3) 滅菌人工海水，並將其置於葡萄糖-酵母萃取物-蛋白腖瓊脂海水培養基 (GYPS)、馬鈴薯葡萄糖瓊脂海水培養基 (PDAS)及人工海水瓊脂培養基 (SA)上培養。將藻體片段上長出之真菌分離成為單一菌株，並依其菌落形態初步分群後，將其核糖體核酸 (rRNA)基因之內轉錄間隔區 (internal transcribed spacer, ITS)序列以美國國家生物技術資訊中心 (NCBI)資料庫中的BLAST比對鑑種。結果顯示分離頻率 (%)，分離出真菌之藻體片段數量/總藻體片段數量×100)最高者為以滅菌人工海水漂洗處理，並培養於G

YPS的健康藻體 (93.86%)；最低者為以4%次氯酸鈉溶液滅菌處理，並培養於SA的死亡藻體 (33.32%)。在健康藻體上分離出119種真菌，死亡藻體上分離出85種真菌。整體上共分離出3,187株129種真菌，其中子囊菌有119種，擔子菌9種，毛黴菌1種。細翼枝菜上出現率最高之優勢菌群為散囊菌目 (28.33%)，其次為肉座菌目 (14.40%)、鎖擲酵母目 (13.62%)、煤炱目 (9.57%)、格孢菌目 (5.90%)及炭角菌目 (5.62%)。豐富度 (abundance)最高之菌種為擔子酵母菌Rhodosporidium fluviale，共分離出346株，佔10.86%；其次為

分離出213株之Aspergillus sp.-1，佔6.68%。不同季節中的結果顯示細翼枝菜上之真菌在溫度較高月份，其物種豐度 (species richness)及豐富度皆高於溫度較低月份。在不同分離培養基上 (SA、GYPS、PDAS)除整體出現率外，其物種豐度並未顯示有顯著的差異。未來應對細翼枝菜上無法培養之真菌其多樣性、生態定位及在宿主之定殖情形做進一步的探討。
