Solsø 1981 primary pollen-count lineage

The primary EPD/PANGAEA pollen profile is a 66-depth, 147-parameter count table for the SOLSOE81 1981 core. Its source text is retained privately under landclim/pangaea/solsoe/ with SHA-256 da790080493ccfe7e37ab16d154e438cfbeb7b0046bc41d7f24499572a0353d0. PANGAEA attributes the data to Bent V. Odgaard and the European Pollen Database under CC BY-NC 3.0. The raw table is not redistributed here.

The source-bound comparison joins those 66 depths exactly to Neotoma collection unit 4303 at site 3432. Decimal centimetre conversion is exact; an earlier float-truncation diagnostic had falsely suggested four 1 cm differences. Across the 9,702 depth × parameter cells, the primary table has 2,881 positive counts and 6,821 zeros. Neotoma records exactly those 2,881 positive NISP observations, no more and no fewer; every matched count is equal. Their total is 128,653. The sample ledger identifies every depth, Neotoma sample ID, positive taxon count and row total. Report SHA-256 is e71e6ef7fb52afd2abf5540d1a003d4008e9520e58a39980296cba88d1003c2b; sample ledger SHA-256 is a4f41777c1b4cbe104aaa7fb78355b9d7ad249bb81b4ace401eb07e9cceef010.

129 PANGAEA parameter names match Neotoma source-reported names exactly. The other 18 each have one unique Neotoma name with an identical 66-depth count vector. The report retains those as numerical source-name candidates, including their positive-depth counts and totals. Some are modernized names; count-vector identity alone is not qualified ecological taxonomy approval. The PANGAEA zero cells correspond to missing rows in Neotoma's sparse positive-observation export. The 128,653 total spans all 147 primary parameters and is not silently treated as a terrestrial pollen denominator or a 31-target LandClim PPE denominator.

The source text and retained Neotoma manifest, sample part and eight observation parts are SHA-checked by the producer. The same primary core's 34 radiocarbon controls were compared separately. These joins establish the 1981 core's count and control lineage; they still do not select the 79 samples in the LandClim II author sequence, identify its chronology, provide age-specific basin geometry or admit any Danish LRA sample.
