The gelatinous mass, I am pretty sure, after much Googling, is a "squid egg mop." Here's another picture of one. Female squids die after they make them. Male squids hang out a bit longer, then they die, too.
The track, I am quite sure, also after much Googling, was made by a horseshoe crab(s). They apparently ascend the beach around this time of year to lay eggs, which seagulls and other birds then feast on:
During the breeding season, horseshoe crabs migrate to shallow coastal waters. A male selects a female and clings to her back. The female digs a hole in the sand and lays her eggs while the male fertilizes them. The female can lay between 60,000 and 120,000 eggs in batches of a few thousand at a time. The eggs take about two weeks to hatch; shore birds eat many of them before they hatch. The larvae molt six times during the first year.
