Deep Sea Cartography

At roughly 7:19 on wednesday morning, a strange opening was discovered at the bottom of the red sea. you have been tasked to map out this anomaly to mark the path for future expeditions. you can use the ARROW KEYS on your terminal to move your vessle and the SPACE BAR to activate your sonar. using the MOUSE we expect you to draw a map of your surroundings and we hope that you may return safely. We do not know what may be down there but be aware that due to the darkness, any creatures that may be down there are likely to be sensitive to any sound that you may make. Good Luck.
