Adult California Sea Lion was laying on the beach at last high tide line. It was alive, and raised its head in response to noise (e.g. dog barking). Report with photos sent to Oregon Marine Mammal Stranding, with return response from Jim Rice.Followup: CSL remained on the beach at least until dark, when warning signs were posted, but was no longer on the beach the next morning.
Fish & Invertebrates:
Driftline:
Small rocks·Kelp or Algae·Shells·Animal casings (e.g. crab, shrimp molt)·Wood pieces·Land-based debris (picnics, etc.)·Plastic pellets·Styrofoam·Ocean-based debris (from fishing boats, ship trash, etc.)
Lots of small plastic pieces in the wrack line.
New Development:
Modifications:
Natural Changes:
Erosion of vegetated foredune
Erosion was evident along the bluff, primarily involving vegetated (sea grass) foredunes The footprints of the creeks at both ends of Mile 99 (Johnson Creek on the north and Crooked Creek on the south) were broadened significantly since the last survey, with banks as high as 5 feet in height.
Comments:
Summary:

Mile 99 seems to have weathered the winter storms with some erosion of the seagrass foredunes, but minimal loss of solid bluff. The creeks bordering the mile to the north and south have carved significantly wider and deeper paths to the ocean. One California Sea Lion was observed alive at the last high tide line, and was reported to Oregon Marine Mammal authorities. Local environmental scientists reported that the beach showed evidence of mole crab breeding activity from the previous night of a full moon. There were fewer people and dogs on the beach than during a summer day of similar conditions (sunny, light winds).

This survey was conducted on Sunday of a holiday weekend, which is likely why more people were on mile 99. The expected shorebirds and seabirds were seen on the offshore rocks, including a large...

Mile 99 is showing the usual changes in sand shifts and creek configurations for winter. The major change from a few months ago is the large amount of non-organic debris in the wrack lines and along...

Mile 99 looks good after the first winter storm of the season. The sand dunes from summer winds are diminished, and the creeks are running higher. Johnson Creek is approximately 8 inchs deep near the...

Last mile survey before upcoming seasonal storms. The wet sand is quite cluttered with kelp piles and clusters of muscles and barnacles. There was a minimal number of shorebirds and gulls. Johnson...

A lovely sunny Fall day to walk the beach. I focused on collecting beach debris along north and south banks of Johnson Creek. There was a signficant amount of plastic debris pieces between 1/2 inch...

Noted a few natural topographic changes to mile 99 since last month, with moving sand dunes and rerouting creeks. Otherwise no concerns with the people, dogs, or wildlife.

My first CoastWatch-based walk on mile 99, which is between 2 creeks, and includes numerous large rock formations on the beach and a public picnic area. I collected 2 containers (approx. 2 gallon...

It was a lovely and very quiet day. Few people on beach, surprisingly. Within 5 minutes walk south of entrance onto beach, I had already collected half a bucket full of small plastics and small piece...

A crowd of 20 -- a big turnout for this beach in the fall -- attracted by a calm foggy day (about to turn sunny) and a high King Tide that made for dramatic surf-watching. The summer buildup of sand...
  • High tide eroding summer sand buildup.

We were sitting on the warm sand measuring a beached bird for the COASST program with Bill Bridgeland and Robin Rauch when a small tick-like animal came scurrying across the sand toward us. Bill was...
  • This was found on the sand near a rock.

Had a break in the storms and caught a great morning. Calm, sunny and in the low 50's. Plant material (wood pieces, small branches), Bull Kelp and seaweed littered the beach due to the storms....
  • Bull Kelp, shown here, and wood pieces and branches littered the beach after major storms.
  • Storm water in the river eroded the foredune and sand bank.  Drop to river was about 4-5 feet.  Dune in the rear of the photo is about 15 feet high.
  • Lepas anatifera on a previously floating plastic bottle.  Also found some on driftwood.

2007

November 6, 2007 - Eric & Sue
Nice calm day with only three people and a dog on the beach. The tide was very low, and I saw very little garbage on the beach. About a half dozen 2"-5" crabs on a rock near Haystack Rock had been...

There were at least eight to ten dead gulls. All had been dead for quite awhile and were near the high tide line. About a half dozen people and one dog. Lots of sea palms and some kelp on beach. Also...

We are filing this report on Mile 99 to document the dead female Salmon Shark (Lamna ditropis) that we found washing up onshore. This week has been very warm, and the wind as been from the south so...
  • Face view of a female juvenile Salmon Shark.
  • This shows the rows of shark teeth.
  • The eye was pecked out by Western Sea Gulls prior to photographing.
  • This shark appears to have been bitten by another shark, but it is not clear whether it was the cause of death or if this happened after the shark died.  The pelvic fins do not have claspers and so this is a female shark.

Crab and Mole crab casings in driftline. Large chunk of styrofoam in surf line and a large fish net next to creek. Watched an Oystercatcher nest on the rock south of Haystack Rock. Large water...
