She glanced up at Lucy. “I’m going to climb down. Is the rope secure?”
Though Lucy knew it would be wiser to await the arrival of Max and Theo to assist them, Jane was so near to the ground even if she fell she’d be okay. She was also as eager as Jane to find out what lay hidden in the darkness below. “It’s secure.”
Jane rappelled down the short distance to the cavern floor and groaned when the harness chaffed her sore skin. Her lamp roamed through the darkness, reflecting off the walls of solid ice. Its surface was covered in large scallops, as if someone had used a giant ice-cream scoop to dig out the ice, giving it an unreal glossy appearance.
“Hello!” she called out. Her voice echoed back at her through the large space. It must be as big as a cathedral.
A drip of water caused her to look toward the sound. Bright blue light erupted out of the darkness. It reflected off the thousands of faceted edges of the sculptured ice and briefly lit up areas of the cavern. Jane stared in fascination when the blue light rippled across an expanse of water a short distance away. She tilted her head up to Lucy. “What was that? It was beautiful.”
Lucy, whose view was limited by the size of the hole and the thickness of the ice, had witnessed the effect of the eruption of blue light. She was unable to see its source, though she had a good idea as to its cause. “Unhitch yourself from the rope and move away. I’m coming down.”
Doubting anything she said would deter the excited microbiologist from joining her, Jane did as instructed and also removed the chaffing harness. “Okay, it’s all yours.”
Lucy grabbed the spike from across the hole, moved a few yards away and screwed it into the ice. After detaching the two ropes from her harness, she tied Jane’s rope to the spike. A hard tug on the rope satisfied her it was secure. While she attached the rope to her harness, small pieces of ice trickled down the side of the crevasse. She looked up. She glimpsed the shadowy figures of Max and Theo through the drifting snow, patches of colour in the whiteness. They were about halfway down. She used her walkie-talkie to apprise everyone of the situation. “You’re not going to believe this, but Jane found a subterranean cavern complete with a body of water. I’m going down to join her so we can explore. Over.”
It came as no surprise to Lucy when Henry tried to prevent her from doing so. “It sounds like a momentous discovery, however, do not enter until we’ve assessed the safety aspects of doing so. The cavern could be unstable. Also, you might contaminate a sealed ecosystem. Over.”
“Henry, the cavern has probably been there for thousands of years. The likelihood of it collapsing the moment we decide to explore it is very remote. Also, it was contaminated when Jane fell into it. I’m not willing to miss this opportunity and I’m going in. Over.”
“I strongly advise against it, but as I’m too far away to prevent you, please be careful and don’t touch anything. Just observe. Over.”
Lucy had already dropped the radio in her pocket and slipped the head lamp over her head. She sat at the edge of the ice hole, climbed through and swiftly slid down to the cavern floor. Jane waited nearby. Lucy untethered herself from the rope and joined her.
“Wow! This place is freaking amazing.” Lucy’s light joined Jane’s sweeping the area. She knelt and examined a patch of green slime covering some of the rocks dotted amongst the ice on the ground. “I think this is algae, perhaps even a new type.”
Jane smiled at Lucy’s excited enthusiasm. “As exciting as you make that sound, I’m more interested in the water and the blue light.”
Lucy stood up. “Let’s go check it out.”
They paused at the edge of the lake where the rocky ground sloped gently into the slightly murky pool, and shone their lights onto the water. The beams refracted off into its depths. A faint mist rose from the lake, evidence its temperature was slightly warmer than its surroundings.
“What caused that blue light?” Jane asked.
“I think it must be some type of planktonic dinoflagellate, probably Noctiluca scintillans.”
A mystified expression accompanied Jane’s glance at the young woman beside her. “That meant absolutely nothing to me.”
Lucy laughed. “In very simple layman’s terms, it’s a type of marine creature called plankton, which displays bioluminescence when disturbed. Let me demonstrate.” Lucy picked up a small piece of ice from the ground and threw it into the lake. As before, the blue fluorescent light appeared and rippled across the water out from the point of the splash.
“So bugs are making this spectacular display?” said Jane.
“Well, plankton, yes. But it’s unusual to find them in a sealed environment like this, but then again, this is the first one I know of so deep beneath the ice that has been explored. It might even be a new species.”
After staring at the water for a few moments, Jane said, “Henry wasn’t too keen for you to come down here.”
Lucy smiled. “He’ll get over it. He worries about us, that’s all. Two people died on one of his previous expeditions. Though he blames himself, it wasn’t his fault.”
“Really? What happened?”
“Henry was leading a group across the ice when a blizzard appeared out of nowhere to envelope them. The two men at the back, who had previously voiced concerns at being dragged into a crevasse if those in front fell into one, untethered themselves from the safety line and got cut off from the others. Though Henry searched, neither they nor their bodies were ever found.”
Jane’s thoughts flicked back to when she had lost Kyle. “That’s horrible,” said Jane. “It explains why Henry’s so over protective of us all.”
They both shone their torches over the lake. The weak beams failed to reach its far side. “We need more powerful torches to explore this cavern properly,” said Jane.
“You’ll have to ask Henry to get someone bring them from base. We’ll also need sample jars, a rock hammer and anything else he can think of we might need. I have a camera with me, but another would be handy, plus the digital film camera to record all of this.”
“Okay, I’ll ask.” Jane used the walkie-talkie to contact Henry.
Henry paced. Though he knew it was reckless of Lucy to enter the ice cavern, he couldn’t blame her youthful exuberance; he had been the same at her age. But she failed to understand the dangers Antarctica constantly threw at its visitors, especially when rash decisions were made. He’d learned from hard experience that death was never far away in remote, inhospitable places like this.
“Henry, are you there? Over.”
Though the reception was weak with a background of static, Henry was able to understand what was said and recognized the voice. “Jane, it’s great to hear your voice. Are you okay? Over.”
“Yes, dad, I’m fine. Over.”
Henry smiled. “Glad to hear it. We were all so worried. What’s this cavern like? Over.”
“It’s fantastic, what little we can see. There’s a lake full of luminous plankton that has Lucy excited, but I’ve seen nothing that would cause NASA’s scan anomaly. The cavern alone wouldn’t do it, but we can’t tell how big it is or see everything that’s down here until we have more powerful lights. We also need some other equipment to take samples. Over.”
“First things first, Jane. Is the cavern stable? Over.”
